The five main reasons for Java’s popularity are:

• Platform independence – Java runs on the WORA (Writing Once, Run Anywhere). A Java code is compiled into an intermediate format (a.k.a. bytecode), which is then executed in the JVM (Java Virtual Machine). So, any system running a JVM can execute Java code. Furthermore, JRE (Java Runtime Environment) is compatible with all three operating systems – Linux, macOS, and Windows.
• Multi-threaded – Java has inbuilt multithreading capabilities, which means that you can develop highly interactive and responsive apps with multiple concurrent threads of activity using Java.
• Object-oriented – Java is a purely object-oriented language. Inspired by C and C++, Java extends the functionality of these languages to become a pure object-oriented programming language. Abstraction, encapsulation, inheritance, and polymorphism are some of its core OOP features. 
• Secure – When it comes to safety, Java incorporates a host of safety features into the runtime systems, including runtime checking and static type-checking at the time of compilation. With these features in place, it is pretty challenging to hack into a Java application from an external source.
• Robust – Java leverages a simple memory management model reinforced by automatic garbage collection. Since Java objects do not require external references, Java code is robust. Besides, it also encourages developers to adopt productive programming habits for developing secure and reliable applications. The more you experiment with different java projects, the more knowledge you gain.
• Open source – Java’s position as the second most trending programming language worldwide ( IEEE Spectrum ) in 2023 primarily rests on it being freely available for use; in other words, it is open source. This makes it ideal for developers and programmers of various competencies looking to build apps of their own. They can even access the latest versions of Oracle JDK and Open JDK free of charge through the Java Development Kit.
• API rich – Consisting of approximately 52 keywords, Java boasts a rich and extensive API (Application Programming Interface). Thus, making projects in Java is easy, with a multitude of methods available for use in any program directly. Developers can accomplish any task with Java API methods, whether handling output input, networking, processing XML, or connecting to databases.
• Community backup – Java’s robust and active community is among the many reasons for its continuing popularity. The Java Community, Stack Overflow, and Java in General are some of the top communities where developers and beginners alike can find assistance when faced with a problem. If you are developing core Java projects or seeking project ideas for Java, you can find extensive and reliable support on these websites from expert developers.
• Documentation support – Another factor contributing to Java’s immense popularity is its detailed documentation feature. Javadoc, a well-documented guide, provides solutions to developers who face problems while coding any application or program.
• Development tools – In addition to frameworks, integrated development environments (IDE), and profilers, Java has an arsenal of various automation, debugging, and editing tools. Java has tools for every type of development project along with various stages of development. Different projects in Java require the use of different tools. These include Maven for building applications, Jenkins for integration and delivery, JIRA for bug tracking and planning, and Splunk for monitoring, to name a few.
• User-friendly – Java offers an easy learning curve with its simple English syntax and use of minimum special characters. This makes it easy for beginners and professionals to master this language. Basic knowledge of programming languages like C and C++ is all that is needed to learn Java and build projects using Java later. Resources are readily available online on various websites, mostly for free.

The mail server on the collector side receives the incoming emails and sorts them electronically in the inbox. Now, the recipient can use their email application to view the received emails. The entire transaction occurs by directly connecting to the mail server through the program, which makes it much safer than the existing email client software.

7. Library management system

This software project is implemented in Java using MS Access database design. It is designed for managing and maintaining libraries in any educational institution through an integrated computerized system. The library management software will allow librarians to operate more productively while handling the typical day-to-day tasks of a library. 

In a traditional library management system, everything is done manually. All the library operations and records, including the number of books, genres of books, names of books, records of the students who’ve issued/returned books, etc., are all done via pen and paper. Naturally, this process requires a significant amount of time, effort, and even human resources. If you are looking for final-year java projects, this is perfect for you.  

The proposed project seeks to solve all the challenges associated with the traditional library management system. Since it stores and manages all the library records in a computerized database, it eliminates the need for manual record-keeping. The software includes different modules, each of which handles and manages specific library operations. Mentioning Java projects can help your resume look much more interesting than others.

By using this software application, librarians and students need not search the entire library to find a book. They can enter the name and author of the book, and the system will display the list of all the possible books available for that search keyword/phrase. This is one of the best features of this library management software.

8. Network packet sniffer

A network packet sniffer is a packet analyzer software used for monitoring network traffic. It is a web-based Java application that facilitates the web-based monitoring of network packets traveling across the system network. It is developed as a desktop application, and this packet sniffer facilitates web-based monitoring of network packets that are traveling over the system network. The primary data captured by this software are the packet source and destination addresses. By using this software application, the Admin can capture network packets and analyze the data received and sent from/to the network. The software helps capture the source of the network packets and the destination address.

The main objective of this project is to establish a set of rules during runtime to prevent hackers from attacking the system software with viruses and malware. Unlike standard network hosts that only track the traffic sent exclusively to them, this software application captures each packet, and decodes it for analysis as the data streams flow across a network. Some of the most commendable features of this software application are:

• 24×7 network monitoring
• Real-time packet capturing
• Advanced protocol analyzing
• Complex network analyzing
• Automatic packet-level analysis
• Comprehensive packet decoding

9. Online bank management system

This is one of the most interesting Java projects to create. This project focuses on developing an online banking system. The main aim is to create an online banking platform that is accessible from any location, so customers need not go to the bank branches for routine banking operations like money withdrawal, money transfer, balance inquiry, etc. 

Bank Management System Project In Java – The Bank Management system (BMS) is a program that allows the Bureau of the Fiscal Service to pay financial institutions for services rendered. BMS also has analytical tools that may be used to examine and approve pay, budgets, and outflows.

Visiting the physical branches of banks is not only time-consuming but can also be hectic, thanks to long queues and waiting times. Not to forget, running to banks for every minor banking task creates an unnecessary burden on bank staff. These issues can be addressed by developing an online banking system that will offer seamless and prompt banking services to customers. However, to use this software application, a user must be registered with the system. To do so, the user has to create a unique username and password for securely logging in to the application.

This online bank management application will provide the following services to customers:

• Customers can view their account details such as type of account, available balance, interest rate on available loans, credit/debit statements, etc. from any remote location.
• Customers can check their transaction history which includes necessary information like transaction time, type, and amount.
• It will display the amount of deposited cash or withdrawn cash along with the date of deposition/withdrawal.

10. Online medical management system

This is another web-based Java project that is designed to create a direct line of communication between doctors and patients. The project is known as “Virtual Medicine Home.” By using this application, patients can book online appointments with their preferred doctors, and doctors can offer healthcare suggestions, e-prescriptions, and view the patient’s medical records, lab reports, etc. The application also lets users look for and connect with blood and eye donors. This is one of the excellent java project ideas for the current time. 

In conventional healthcare service systems, all medical management operations are manual. The problem is more pronounced in remote and rural areas that lack proper medical infrastructure, qualified healthcare professionals, and sophisticated medical equipment. This is one of the java projects for beginners. Furthermore, there are no provisions for recording and storing medical data. This online medical management system can help bridge all these problems by linking doctors and patients directly. 

The application has two modules — an Admin module and a Doctor module. The Admin module manages the online software system, and the Doctor module allows doctors to interact with patients. Anyone can access the services provided by this app from any location via the Internet.

11. Online quiz management system

One of the best ideas to start experimenting you hands-on Java projects for students is working on online quiz management. This Java-based application proposes to create an online discussion platform that will consist of a wide range of questions on different topics, fields, and subjects. By creating a user-friendly environment of Bluebook implementation, this application is a resourceful tool for individuals who wish to practice mock quizzes and tests. Online quiz management system is one of the interesting java projects. 

In this project, you will build a comprehensive online platform for managing both quiz competitions and the participants in the different teams. This application can be used by academic institutions and any organization willing to find suitable candidates through the process of quizzing. 

The application permits multiple admins, each having their unique user id and password. While admins can create an “n” number of participating teams for a quiz, they can also set an “n” number of rounds for the quiz. All the participants will automatically receive the questions, and the teams will have to answer within an allotted time.

In case a team is unable to answer a question or gives the wrong answer, they’ll receive a negative marking. The teams having the lowest average score will be eliminated, and the remaining teams will continue to compete in the next level. This will continue until the winner is declared. The scores for each team will be automatically updated. And this is the perfect idea for your next Java project!

12. Online Survey System

The main aim of developing this online survey system is to conduct an online survey on different topics for the users. This is a project for creating an online survey system using Java as the foundation. The focus of the project is to build an online platform that can efficiently collect the viewpoints of the target audience of a survey via the Internet. This application can launch online surveys and also send email notifications.  Any organization in any industry can use this application to conduct online surveys to obtain necessary information from their target audience groups. 

In this survey application, only the users authenticated by the Admin can cast their vote and express their opinion on a particular issue or topic. Once the users submit the votes, the software will collect them using the ratio button or checkbox. It will then automatically add the votes to each alternative and display the result after the deadline of the survey.

The main features of this online survey system project include:

• It is coded in Java with MySQL server database.
• It can hide the identity of users/voters, thereby collecting all the information in confidentiality.
• It collects the votes using the ratio button or checkbox.

13. RSS feed reader

The goal of the RSS feed reader project is to minimize the delay between the publication of new content on the web and its appearance on the reader/aggregator. It allows the retrieval of the latest content posted on a website quickly on the aggregator, thus, making the content readily accessible to the users for reading. The RSS feed reader management system is equipped with improved content monitoring policies for all RSS feeds. 

The existing aggregator management applications use the homogeneous Poisson model that relies on a specific data source (either a webpage or RSS feed). As a result, these applications cannot adapt if the data source changes. They do not even have well-designed monitoring policies. This project incorporates and implements new content monitoring strategies to overcome the drawbacks of the existing aggregator management applications. The new RSS feed reader leverages a non-homogeneous Poisson model and delays matrices.

This RSS feed reader management system investigates the techniques used by RSS aggregation services to monitor web content and to retrieve the data promptly using minimal resources, to enable readers to access the content without delay. The project focuses mainly on the server-based aggregation scenario.

The proposed model has the following functional requirements:

• It should be able to provide information from disparate data sources to all users.
• The system should be able to run efficiently using minimal system resources.
• The time delay must be minimized so that users can view the data quickly on their feed.
• The aggregated content should be converted into a document format compatible with browsers.
• The RSS content must be monitored at frequent intervals.

14. Smart city project

The Smart City project is a web-based software application built to store all the essential details of a city. Cities and urban areas witness a massive wave of people coming from every corner in search of jobs, education, and even a better lifestyle. In the initial days after the move, people don’t know the main facilities, attractions, and services offered in the city. The smart city project seeks to address that by creating an integrated platform to store essential and related information to guide newcomers in a city.

The application will provide visitors, students, and job seekers information like hotels, renting facilities, transportation services, healthcare services, airline ticket booking, shopping landmarks, emergency helplines, and basically every information that one needs when in a new city. It is like a smart city guide for visitors.

Users can connect to the application via the Internet and browse all the smart city web pages to get the details they need. Users can see the entire map of a city along with the important landmarks. This will make their movement across the city much more comfortable. Mentioning java projects can help your resume look much more interesting than others.

The smart city application has five modules:

• Administration module – It is the central controller of the application. It uploads all the new information on the site and authenticates user profiles, and supervises the maintenance of the other four modules.

16. Supply chain management system

This is one of the interesting Java projects. Supply chain management refers to the management of businesses interconnected over a network. It includes a whole range of management procedures like handling, storage, and movement of raw materials, inventory, and transporting finished goods from the source to its final destination.

This project aims to smoothen the supply chain management process by closely monitoring the dealers and clients and continually tracking the products through the different points in the supply chain. Using this application, a company can directly communicate with its clients, obtain the product requirements, manufacture the product to fit those requirements, and finally ship it off to the client. 

This project uses JSP, JDBC, and HTML for the front-end and MS Access as the back-end database. It is a web-based application that will automate the system of communication between the management or admin, dealers, and clients of the company. There are three modules in this application:

• Admin module – The Admin uses this module to check information on the manufactured products, newly launched products, and products that must be delivered to the clients.
•  Dealer module – This module keeps track of all the essential information concerning the dealers, particularly the record of items. Dealers can generate and update the item list for a product using this module. 
• Client module – The client uses this module to provide the necessary specifications of a product. The client feedback is processed through this module and forwarded to the Admin. 

By using this application, the clients can directly convey their product requirements to the manufacturer, who then contacts multiple vendors to acquire the necessary resources for making the product. The dealers usually create a list of items as per the product information provided to them, after which the manufacturer selects the materials that best fit the specifications given by the client.

Then, the selected list of items is forwarded to the inventory department for processing, after which the manufacturing begins. Once the production is complete, the accounts department calculates the raw materials costs and manufacturing costs to generate the total bill. Finally, the product, along with the invoice, is shipped to the client. The client is free to offer feedback on the received product.

17. Virtual private network

VPN is one of the trending java projects. The goal of building this virtual private network (VPN) is to extend a private network across a public domain (for example, the Internet). A VPN is created by setting up a point-to-point virtual connection via traffic encryption, dedicated connections, or virtual tunneling protocols.

There are three interconnected modules in this VPN project: 

• Administration module – This module monitors all the office operations and manages the staff details. 
• Marketing module – This module handles everything related to the marketing operations of the software application.
• Training module – This module manages all the technical operations like software testing, networking, call center, and J2EE training.

Confidentiality, authentication, and data integrity are the three core elements of this VPN security model. The other pivotal features of this application are:

• It allows for the addition of new clients, a feature better known as “scalability.” This feature allows a company/organization to accommodate new clients in the network as it expands. 
• It uses a remote backup server to prevent the system from failing due to sudden crashes. Since a VPN handles a large volume of files that are created every day, it is crucial to have a remote backup server to process all the requests coming from the client to the server and vice-versa.
• It uses a remote monitoring system to keep track of the activities of every client or individual connected to the VPN. This ensures that the privacy and security of the network remain intact.
• As is true of all VPNs, this VPN application, too, has the provision for certification in the system. When two or more LAN (Local Area Network) systems interact, certification is mandatory to protect the system’s security. 
• It triggers and sends acknowledgment signals to notify clients of successful data transfer (whether or not the data has successfully reached the desired destination).

The comparative analysis of Java frameworks: Spring Boot, Micronaut and Quarkus

The aim of the work is a comparative analysis of three frameworks designed for building web applications for the Java programming language: Spring Boot 2.4.4, Micronaut 2.5.4 and Quarkus 1.13.4.Final. Test applications were prepared, equipped with the same functionality as used in the experiment consisting in measuring the server response times to a POST request – performing the data entry into the database. For each test application, the scenario aimed at measuring the time of handling requests under various load conditions was repeated five times. During each repetition of the scenario, the load which was the average number of requests sent per second by virtual users was increased. In parallel with performance tests, the reliability of the test applications was measured. Reliability was defined as the percentage of requests sent to the server that ended in a failure. The comparative analysis also took into consideration the volume of the code of the test applications based on the selected frameworks. The performed analyses showed that in terms of all the criteria considered in this work Micronaut proved to be the best framework.

Comparative analysis of connection performance with databases via JDBC interface and ORM programming frameworks

The tools investigated included JDBC drivers and Object-relational mapping (ORM) frameworks. A survey based on 8 different criteria was conducted to determine the most effective method and tool for working with relational databases when developing Java applications. The weights of the criteria were determined through a survey of Java programmers and computer science students.

Performance Evaluation of Java Programming Strategies

Java is one of the most demanding programming languages nowadays and it is used for developing a wide range of software applications including desktop, mobile, embedded, and web applications. Writing efficient Java codes for those various types of applications (which some are critical and time-sensitive) is crucial and recommended best practices that every Java developer should consider. To date, there is a lack of in-depth experimental studies in the literature that evaluate the impact of writing efficient Java programming strategies on the performance of desktop applications in terms of runtime. Thus, this paper aims to perform a variety of experimental tests that have been carefully chosen and implemented to evaluate the most important aspects of desktop efficient Java programming in terms of runtime. The results of this study show that significant performance improvements can be achieved by applying different programming strategies.

An improved Framework for Biometric Database’s privacy

Security and privacy are huge challenges in biometric systems. Biometrics are sensitive data that should be protected from any attacker and especially attackers targeting the confidentiality and integrity of biometric data. In this paper an extensive review of different physiological biometric techniques is provided. A comparative analysis of the various sus mentioned biometrics, including characteristics and properties is conducted. Qualitative and quantitative evaluation of the most relevant physiological biometrics is achieved. Furthermore, we propose a new framework for biometric database privacy. Our approach is based on the use of the promising fully homomorphic encryption technology. As a proof of concept, we establish an initial implementation of our security module using JAVA programming language.

Research on the Transformation of Teaching and Research Form of Professional Teachers in Blended Learning at Colleges and Universities – Taking the Java Programming Course as an Example

In view of the current situation that offline teaching is the main mode of teaching Java Programming in higher vocational schools, this paper introduces the online and offline hybrid teaching method and expounds it from the aspects of blended learning design, teaching organization, and implementation. At the same time, combined with the characteristics of blended learning, this paper proposes that under the new mode, teachers should actively change the form of teaching and research, the teaching mode, and the role of teachers, take students as the center, and build an independent and effective classroom.

LSB-based Audio Steganographical Framework for Securing Data in Transit

The benefits that individuals and organizations derive from the digital era comes with its own challenges. Globally, data has become one of the greatest assets for decision making and operational improvements among businesses, government agencies and even individuals. Data on its own and at its source does not make so much contribution to business processes. Data is transmitted from one location to another towards attainment of its goal as a critical resource in decision making. However, data including sensitive or confidential ones are transmitted via public channels such as the Internet. The data so transmitted via the Internet is vulnerable to interception and unauthorized manipulation. This demands that data in transit is protected from the prying eyes of the malicious internet users. One of such strategies for transmitting data via public channels such as the Internet without attracting attention from intruders is steganography. In this paper, the least significant bit algorithm was used with an audio file for hiding data in transit. The algorithm used in this research proves to be one of the simplest ways of securing data using audio steganography. The method employed the LSB technique by using audio files as the stego object for the final implementation in the Java programming language. The experimental results proved to be one of the best methods of implementing steganography. The accuracy of the stego objects shows high quality, and similarity scores with an improved processing time.

The player loses when the snake touches the boundary and the final score is displayed.

• How To Setup Your Java Environment

Before you start coding in Java, it's essential to have your coding environment properly set up and ready for action.

Being a compiled language that runs on a wide range of devices through the Java Virtual Machine (JVM), Java requires a bit more setup compared to interpreted languages like JavaScript that run directly in web browsers.

Here's how to set up a Java development environment on most operating systems.

Install a Java Development Kit (JDK)

First and foremost, you need the JDK, which includes the Java Runtime Environment (JRE) and the compilers and tools needed to compile and run Java applications.

• Download the JDK: Visit AdoptOpenJDK or Oracle's official Java site to download the JDK. I recommend choosing the LTS (Long-Term Support) version for stability.
• Install the JDK: Run the installer and follow the instructions. Make sure to set the JAVA_HOME environment variable to the JDK installation path and add the JDK's bin directory to your system's PATH . This is crucial for making Java commands accessible from your command line or terminal.

Verify Installation

After setting up, verify that everything is working correctly.

To begin, open a terminal or command prompt and run these commands to check the installed Java and Java compiler versions, respectively:

Then, try creating a simple Java program and compile it using:

Then run it with:

This should confirm your JDK is correctly set up.

Install a Java IDE or Code Editor

You'll need an IDE or code editor that supports Java syntax highlighting and potentially IntelliSense for code completion.

Eclipse, NetBeans, and IntelliJ IDEA are some of the most popular choices and three of my personal favorites.

That said, I'd also consider Visual Studio Code (VSCode) as this is a hugely popular choice among developers for various languages thanks to its extensive and lightweight feature set and vast library of extensions.

If you do go the VSCode route, head to the VSCode extension marketplace and install the ‘Extension Pack for Java’ from Microsoft, and you’ll be good to go.

Install Git [Optional but Recommended]

If you're really new to coding, you might want to skip this step, but even then, I'd really recommend becoming familiar with Git as soon as you can.

If you want the TL-DR, Git is a version control system that lets you track changes in your code and collaborate with others.

While this step is not strictly necessary for Java development, it's a best practice, especially for larger projects or when working in a team.

Simply download Git from the official Git website , and during installation, you can accept most default settings. That said, you might want to choose your preferred text editor and ensure that Git is added to your system's PATH.

• Wrapping Up

And there we have it! If you've taken the time to build these 10 Java projects, you should be feeling much more competent and confident with Java.

You'll also have a burgeoning Java portfolio that's packed full of interesting and practical Java projects, each demonstrating your dedication and abilities.

I also hope you enjoyed following along with my step-by-step tutorial on the first three Java projects!

My motivation with these Java tutorials is to guide you through the nuances of Java development while also giving you hands-on experience that you'd usually only get when taking a Java course.

Here at hackr.io , we're huge fans of project-based learning, so I hope these Java projects have bolstered your confidence and sparked a deeper interest in web development or any other form of Java development.

Remember, the journey doesn't end here!

With new projects and step-by-step tutorials regularly added to this page, be sure to check back often for new opportunities to refine your Java skills and expand your portfolio.

Happy coding!

Key takeaways.

• Java 11 has reached parity with Java 8 in terms of market share.
• Quarkus, introduced after Micronaut and Helidon, continues to be a popular framework and has "crossed the chasm" into the Early Majority space.
• Containers have broken through and are now the way that the majority of Java applications are deployed.
• Microsoft furthers its commitment to Java with the release of their own downstream distribution of OpenJDK and having joined the Java Community Process. Microsoft Build of OpenJDK is a new participant in the OpenJDK downstream distribution space.
• Spring Framework 6 and Spring Boot 3, scheduled for GA releases in 2022, will be a major overhaul of these projects to adopt modularity. Spring Native has emerged as a new tool to convert existing Spring Boot applications, written in Java or Kotlin, to GraalVM native images.
• MicroStream has emerged as a new participant in the Java ecosystem.
• After years of stagnation, VS Code is shaking things up in the Java IDE space.

This article provides a summary of how the InfoQ Java editorial team currently sees the adoption of technology and emerging trends within the Java space.

We focus on Java the language, as well as related languages like Kotlin and Scala, the Java Virtual Machine (JVM), and Java-based frameworks and utilities.

We discuss trends in core Java, such as the adoption of new versions of Java, and also the evolution of frameworks such as Jakarta EE , Quarkus , Micronaut , Helidon , MicroProfile and MicroStream .

This report has two main goals:

• To assist technical leaders in making mid- to long-term technology investment decisions.
• To help individual developers in choosing where to invest their valuable time and resources for learning and skill development.

This is our third published Java trends report. However, this topic has received ample news coverage as we have been internally tracking Java and JVM trends since 2006.

To help navigate current and future trends at InfoQ and QCon, we make use of the “crossing the chasm” mental model for technology success pioneered by Geoffrey Moore in his book of the same name. We try to identify ideas that fit what Moore referred to as the early market, where “the customer base is made up of technology enthusiasts and visionaries who are looking to get ahead of either an opportunity or a looming problem.”

As we have done for the 2020 and 2019 Java trend reports, we present the internal topic graph for 2021:

For context, here is our internal topic graph for 2020

Aside from some new technologies having been identified in the Innovators space, notable changes include: defining versions of Spring (and their related projects), Jakarta EE and Scala into different categories. We decided on this approach to avoid generalizing these technologies into one category when varying degrees of maturity and adoption exist.

Spring Framework 6 and Spring Boot 3, scheduled for GA releases in late 2022, will be going through an overhaul to adopt modularity and will require JDK 17+ and Jakarta EE 9. A preview has recently been made available with the first milestone release of Spring Framework 6.

Introduced at the beginning of 2021, Spring Native is a new tool to convert existing Spring Boot applications, written in Java or Kotlin, to GraalVM native images and is in the very early stages of development.

Scala 3, released earlier this year , was overhauled with many new features, new syntax and the much-anticipated new Dotty compiler that has been under development for a number of years.

Earlier this year, Microsoft furthered their commitment to the Java programming language when they introduced Microsoft Build of OpenJDK, their own downstream distribution of OpenJDK.

AdoptOpenJDK joined the Eclipse Foundation and was immediately renamed Adoptium. The transition to Adoptium included the creation of an Eclipse Working Group and a split of AdoptOpenJDK into multiple sub-projects under the Adoptium top level project: Eclipse AQAvit , Eclipse Temurin and Eclipse Temurin Compliance .

What follows is a lightly-edited summary of the corresponding discussion on various topics among several InfoQ Java Queue editors and Java Champions:

• Michael Redlich , Senior Research Technician at ExxonMobil Research & Engineering and Java Queue Lead Editor at InfoQ
• Ben Evans , Senior Principal Software Engineer at Red Hat, Java Champion and Java Queue Editor at InfoQ
• Erik Costlow , Director of Developer Relations at Contrast Security and Java Queue Editor at InfoQ
• Johan Janssen , Software Architect at Sanoma Learning and Java Queue Editor at InfoQ
• Karsten Silz , Senior Full-Stack Java Developer and Java Queue Editor at InfoQ
• Monica Beckwith , Senior Principal Engineer at Microsoft and Java Champion
• Ana Maria Mihalceanu , Developer Advocate at Red Hat and Java Champion
• Reza Rahman , Principal Program Manager for Java on Azure at Microsoft
• Simon Ritter , Deputy CTO at Azul and Java Champion

We feel this provides more context for our recommended positioning of some of the technologies on the internal topic graph.

Beckwith : Java is now a more vigorous enforcement of OOP principles via JEP 403: Strongly Encapsulate JDK Internals . Vector computation via a platform-agnostic Vector API. The language additions, such as Records, and JVM improvements, such as project Valhalla, remove many verbosities and further embrace the concept of immutability, thus providing opportunities for performance optimizations.

Mihalceanu : This year pleasantly surprised Java developers with both LTS and non-LTS Java releases. The Java 17 release was the confirmation that many of those preview features are now generally and long-term available. It also added a sense of urgency for some projects that still run on Java 8 to migrate to a newer version. Java 17 is the LTS that fulfilled the lifelong dream of having helpful NullPointerExceptions.

Rahman : As always, all parts of the Java ecosystem remain lively. This speaks to the fundamental strength of Java. I think Java SE 17 has been particularly well received, especially features like Records. Runtimes like WildFly, Payara and Open Liberty are adopting Java SE 17. While some developers have adopted Java SE 11, Java SE 8 remains remarkably sticky. It is possible Java SE 17 will finally change that.

Ritter : The release of JDK 17 has been significant. This means developers now have a new long-term support (LTS) release from all the OpenJDK distributions. For those not wishing to upgrade their Java version every six months to remain as stable and secure as possible, this is an important release. I like the way that we are seeing more small language features added to the platform more quickly than we've ever seen before. This is thanks to the six-month release cadence, which also makes both incubator modules and preview features practical. There are also some interesting developments in how the JVM can work in a cloud environment such as the new project in OpenJDK called co-ordinated restore at checkpoint (CRaC). Features, like records, are great for developing new code.

Evans : The release of Java 17 LTS, and the ability to finally start deploying code that leverages Records and Sealed Types, as well as JFR Streaming for monitoring groups of JVMs. The path towards standardization in the Observability space - especially OpenTelemetry. Early signs of a consensus emerging around what it means for Java to be statically deployed ("Static Java"). I also think Panama will be a bigger deal than people expect.

Downstream Distributions of OpenJDK

Costlow : There are too many non-differentiated JDK distributions out there now. Microsoft has one, Eclipse has Adoptium with Temurin, Oracle has theirs and an OpenJDK build, Azul, AWS Corretto, Red Hat, Liberica, SAP Machine, etc. I'm seeing a proliferation of these, but it's hard to keep them straight. Snyk's  survey  seemed relatively in line with what I see in terms of usage. Given that they're all compatible, I'd like to see a "Just get me OpenJDK" randomizer in the marketplace to remove a decision for new junior Java devs. The Eclipse branding in particular is confusing: Adoptium is a group inside Eclipse, which is also a group. Temurin is the thing you use and it is OpenJDK. Imagine learning Java on your own and reading this sentence: "Eclipse Temurin is the name of the OpenJDK distribution from Adoptium." Fewer brand names is better.

Janssen : Liberica, which is from Bellsoft, actually offers quite some interesting products which differentiate them from other JDK vendors. For instance, a full JDK which still contains JavaFX. I only know of ojdkbuild which offers a similar build. Next to that, they have more variants of the JDK and the JRE. Azul supports non-LTS versions with minor updates for a longer period of time. Some vendors offer Docker images, etc. So there are some differences, but it's hard for end users to compare them and make a good decision about which one to select.

Java EE/Jakarta EE

Rahman : The transition from Java EE to Jakarta EE is one of the largest and most significant technology transfers in our space. That is finally on solid ground with Jakarta EE 9.x. It is very good to see how Jakarta EE 10 is now progressing towards a release early next year. It looks like many of the items in the Jakarta EE Ambassador's Contribution Guide are materializing, closing some long-standing gaps. I think this is a big relief to long term Java EE users. I am also very happy to see Jakarta EE 9.x building momentum. Most runtimes have adopted the javax to jakarta namespace transition including Tomcat and Jetty. Spring Framework 6 is committed to adopting both Java SE 17 and Jakarta EE 9. Similarly, MicroProfile 5 is transitioning to Jakarta EE. According to the 2021 Jakarta EE Developer Survey , a substantial number of developers have already transitioned to the jakarta namespace or are planning to do so. The Jakarta EE 10 Core Profile is paving the way for Quarkus and Helidon becoming fully compatible, the MicroProfile Config API is transitioning to the new Jakarta Configuration specification and the same is happening with MicroProfile Context Propagation. It is possible the same will happen with the MicroProfile REST Client and JWT Propagation.

Redlich : With the release of Jakarta EE 9, tooling vendors can support the new jakarta package namespace, development teams can test migration of their applications to the new namespace, and runtime vendors can test and deliver options and capabilities that support migration and backwards compatibility with Jakarta EE 8. Jakarta EE 9 may also be considered a foundation for innovation to drive new features in Jakarta EE 10 and beyond.

GraalVM/Spring Native

Mihalceanu : Building a native executable is another topic often marked as “most wanted” as the race for smaller, faster containerized applications continues.

Rahman : It is also very good to see that Spring Native is making progress.

Costlow : I like seeing the role of native apps taking shape, but disappointed by the lack of an actual specification or working group. It seems to be kind of "you get whatever GraalVM happens to do" and it behaves differently at times than a standard JDK - similar but not the same.

Janssen : Spring Native competes with all the GraalVM and other frameworks with fast startup times and low memory usage.

Silz : Once Spring Boot supports native compilation with GraalVM, fast and small native Java programs will go mainstream. This makes Java more competitive for serverless solutions and may help it in the microservices arena. I say "may" because as of today, I think that the JVM JIT still has better throughput/performance for long-running processes than GraalVM. Either way, that'll get a lot of press and make Java more competitive overall.

ARM64/Windows on ARM

Beckwith : ARM64 is now commodity hardware. As a result, the presence of Java development kits and the Java runtime environments optimized for deployment on ARM64 have gained mainstream popularity.

Silz : Java 16 supports Windows on ARM. But I think only Java 17 with ARM on macOS will blow the doors wide-open. I believe about a quarter of all Java developers use Macs. And by the end of 2022, they can only buy Macs with ARM. I expect that this will push both Windows and Linux on ARM to get better, too.

Jakarta EE and MicroProfile Alignment == Cloud Native for Java

Redlich : The MicroProfile and Jakarta EE Working Groups, two complementary initiatives under the auspices of the Eclipse Foundation, have collaborated to form a Cloud Native for Java (CN4J), an alliance to define Jakarta EE and MicroProfile positioning and alignment, both branding and technical for cloud-native technologies.

Rahman : It is a pleasant surprise to see Quarkus making well-earned headway with both Java EE and Spring developers. It is also very good to see Jakarta EE and MicroProfile alignment finally happening.

JavaFX/Gluon

Costlow : I am extremely impressed at the work that Gluon is doing to make a single JavaFX codebase run across everywhere. Web was the missing piece from before and, frankly, client Java now seems cool again.

Adopting Modularity

Silz : I think that JPMS tries to solve three problems: class loading woes for app servers; better structuring of the JDK and all Java applications; and reducing the JVM footprint for deployment/runtime. But at least when JPMS finally launched after multiple delays, there were good enough solutions for these problems already: OSGI for class loading; Domain-Driven Design/Clean Architecture/Modulith/ArchUnit tests for Java program structure; and ahead-of-time compilation for reduced JVM footprint. As few unreliable data points we may have, they all show usage of Java 8 and older either being greater than or equal to that of Java 11 and later. I think this is partly because modules gave Java 9+ the reputation of being "hard to upgrade to from Java 8," as Mark Reinhold acknowledges . That's an unintended consequence of JPMS. And it means that at least half of all Java developers can't use the Java advances of the last seven years because they're stuck on Java 8. The opportunity cost of working on modules for probably 7+ years means that many other Java improvements either fell to the wayside or only appeared in Java 10 and later. The var keyword for variables, the new switch syntax, and Java records reduce a lot of the boilerplate that Java's infamous for. If those were in Java 9 instead of Java modules, I think Java would be in a better place now because it had better developer productivity.

What Has Changed Since Last Year?

Beckwith : Many architects and developers have tamed the GC (garbage collection) pause times due to the improvements to the existing collectors. Many others have tamed the tail latencies by transitioning to low-latency, adaptive GCs for their workloads.

Evans : Java 11 has essentially reached parity with Java 8 in terms of market share. Containers have broken through and are now the way that the majority of Java apps are deployed. Quarkus continues to mature and gain ground and new fans.

Redlich : A few Eclipse Foundation Working Groups have been established: MicroProfile, OSGi and Adoptium (formerly known as AdoptOpenJDK). The MicroProfile Working Group and the Jakarta EE Working Group have collaborated on a Cloud Native for Java (CN4J) Alliance initiative. Microsoft furthers its commitment to Java by creating its own downstream distribution of OpenJDK, Microsoft Build of OpenJDK, and by joining the Java Community Process.

What is the Java Community Saying?

Beckwith : Pattern matching for switch statements, native image, cloud native-JVM, and JVM on accelerators, project Loom and Graal.

Mihalceanu : Upgrading. Because the Java language evolved, framework features flourished as well. In my experience, writing clean and secure code promptly depends on the practices shared by a team. Nowadays, it is possible to minimize the time spent developing or fixing code with continuous testing and fewer local configurations thanks to some framework built-in capabilities.

Rahman : Java SE 17 and Quarkus are enjoying the limelight. Kubernetes remains wildly popular. There is early enthusiasm around Spring Native. Folks in the open standard Java community are watching Jakarta EE 10 and MicroProfile/Jakarta EE alignment closely. There is something good happening pretty much for everyone in the ecosystem.

Ritter : The focus for pretty much all developers, at least when working on new development, is how to make the most effective use of the cloud, especially through a microservice architecture. Leveraging containers and technologies like Kubernetes and Spring Boot are very powerful when writing these types of applications. I hear a lot of discussion about how to use these.

Evans : Java 17, Loom, Quarkus.

What’s New and Exciting That We Didn’t Expect?

Beckwith : I had anticipated the richness of the Java ecosystem and the different JDK vendor flavors of the Java Dev Kits offerings. Still, the sheer participation and the agreement towards the accelerated release cadence were a welcome surprise.

Mihalceanu : What I love about Java is that each release adjusts both the language and the experience of developers. Enhancements such as the new date formatter for period-of-day introduced in java.time.format.DateTimeFormatter and DateTimeFormatterBuilder classes, pattern matching with switch, or the default method toList() in java.util.stream.Stream interface help developers to write cleaner and easier to read code.

Ritter : Looking at the Java platform, there wasn't anything we didn't expect and that's a good thing. Now that new features use JEPs to define what they are intended to do, we have a clear roadmap of the things that will be included in Java looking some years into the future. This means developers can be comfortable that there are not going to be big changes that impact backwards compatibility, at least not without plenty of time to evaluate and discuss them.

Evans : A new focus on warm start / suspend-and-resume / CRaC technologies from a number of providers, including Azul and Red Hat.

Redlich : The emergence of MicroStream, a Java persistence company. While their history goes back to 2013, the company was formally founded in 2019. Since then, they open-sourced MicroStream earlier this year with the release of MicroStream 5.0 and has collaborated with MicroStream has been integrated with Helidon and has just released version 6.0.

Silz : After years of stagnation, VS Code is shaking things up in the Java IDE space. It's something new: A cross-platform, cross-language IDE that's fast, has great plug-ins, and is loved by its users! If that sounds like "Eclipse IDE 20 years ago", you're right! VS Code recently boosted its Java capabilities. I expect it to become the best free Java IDE. I think Eclipse recognized that threat and created a Working Group to coordinate a defense. I'm not sure how much IntelliJ will be affected. One exciting side effect of using VS Code for Java development is that you can easily develop with non-JVM languages. I don't think you can do that in Eclipse at all, or only in a limited way. You can develop with non-JVM languages using JetBrains "All Products Pack", but then you have to launch different IDES that don't share settings, plug-ins, or keyboard shortcuts.

The Java Community

Mihalceanu : I started my Java journey while in university, learning that Java supports Object-Oriented Programming with design patterns and coding best practices. As a professional, I am happy to see that throughout the time, the language has embraced other paradigms as well: functional, reactive thus giving more implementation options without losing the readability. How to choose between each model? Occasionally profile your application, spot bottlenecks, and improve your implementation logic. Yet, no advancement is possible without people. The Java Community is large, vibrant, and welcoming, present both physically and virtually all for one purpose: to share knowledge, improve ourselves, and succeed when facing problems.

Please note that the viewpoints of our contributors only tell part of the story. Different parts of the Java ecosystem and locales may have different experiences. Our report for 2021 should be considered as a starting point for debate, rather than a definitive statement, and an invitation to an open discussion about the direction the industry is taking.

“Our world, moved by Java”, Take a moment to contemplate this phrase. Java is one of the most commonly used programming languages. It is also used as the server-side language for most of the back-end development tasks, like those concerning Android development and Big Data. Java is also used for desktop computing, other mobile computing, games, and numerical computing. The popularity of Java is further evidenced by 90 per cent of all Fortune 500 companies using Java. In this article, we’ll be looking at 15+ exciting Java project ideas/topics for you to explore and practice.

Any layman can be a good developer, no matter if you possess a certain gene code to accomplish this or not. That being said, putting in the effort and harbouring the correct mindset is inevitable to accomplish this. Creating Java projects will assist you to hone your skills on real-life projects and amplify your spirit as a developer. This is the sole way to know if you own a pragmatic grasp of the theory you’ve learned. Functioning on these Java projects will let you equip yourself for a job.

The theoretical knowledge that you have is not of utmost importance, employers are interested in how you are able to translate the knowledge in a practical setup. You should create a portfolio of the tasks you have accomplished so far. So, when you interview for the role of developer, you will have solutions, code, apps, and projects, to exhibit to the recruiters. The portfolio will emphasize your strong points and recognize flaws that need modification.

Confused about your next job?

Reasons why software companies choose Java for developing enterprise applications:

• The software industry adopted Java as it made development a pleasure, resolved problems with distribution, and lessened the pang of continuously porting across platforms.
• As Java is an object-oriented language, it is huge and secure. Java programs are composed independently of the platform in bytecode language, which lets the same program work on any machine that is equipped with JVM. It is a realistic and practical approach to software design. Java objects envelop data and behaviour so that code can be used again, thereby making the process of testing and troubleshooting easier.
• Java’s popularity grew when people learned how Java could solve their hardships on servers – making productivity, execution, and scalability reach new levels.
• Java has demonstrated its supremacy over other languages from server-side scaling of multi-tier architecture to internet distribution of software, to the cloud-native deployments, to taking benefit of continuously upgrading hardware architectures and a whole lot more.

Here’s a list of ideas for beginners to try with Java

With the growing trend of hacking attacks, everyone should create different and complex passwords for their diverse accounts to keep them secure. Remembering every password is not humanly possible and noting it down somewhere is not a wise idea. Hence, people take the help of Password generators to create strong and complex passwords for their accounts. To generate such functionality all by yourself, you can take advantage of the function that java offers. Whenever a user is developing an account on a new website, you can use that program to develop a password. To take the safety of the password a notch above, you can enforce such functionality so that it saves passwords in encrypted form. To incorporate this, you need to study the fundamentals of Cryptography and Java Cryptography Architecture.

The idea of this project is to create a core java project that can accumulate the viewpoint of a targeted audience of a survey through the Internet. Based on that, the app can send the targeted audiences promotional emails and can launch online surveys. Any business can make use of this type of software to assemble feedback regarding the services or products they offer. We can build such functionality so that only registered customers can cast their responses. The main attributes of the app should be:

• The apps are programmed in a way that they should be compatible with various databases like SQL and NoSQL.
• Customers can submit their reactions anonymously.
• Should be installed at a doable cost.

People find it challenging to build their resumes. The concept of this java project is to make this process smooth for the customer. The project streamlines the job of designing a resume for an individual.

We can choose a few industry-accepted, well-crafted resume templates, and request the user to incorporate the details he/she wants to add to the resume. After imputing all the necessary information, a personalized resume can be rendered in pdf and doc format by selecting a single button. The app should own the following features:

• Engaging resume template.
• Update each piece of information as per the user’s needs.
• It should have the functionality to publish the resume instantly.

In our childhood, nearly all of us enjoyed playing classic snake games. Now we will try to enhance it with the help of Java concepts. The concept appears to be easy but it is not that effortless to implement.

One ought to comprehend the OOPs concept in detail to execute this effectively. Furthermore, ideas from Java Swing are used to create this application. The application should comprise the following functionalities:

• The Snake will have the ability to move in all four directions.
• The snake’s length grows as it eats food.
• When the snake crosses itself or strikes the perimeter of the box, the game is marked over.
• Food is always given at different positions.

Data visualization is a key part of the state-of-the-art business led by Data Science, Business Analytics, and Business Intelligence. It indicates the visual depiction of data in a pictorial arrangement. This is a powerful java project for apprentices. This information representation project is tied in with providing a synopsis of the plan and usage guidelines in information perception. The destinations of this task are to give clear and compelling correspondence of the experiences wrapped up in the information via appropriate graphical or pictorial depictions.

It depicts the hub availability in systems administration as information visualization. You can use a mouse or a trackpad to find it in different areas. The most useful part about the task is that you can enhance and modify the product highlights and capacities as demonstrated by your prerequisites.

This java project is a contemporary take on the classic electricity billing system where a person gathers data from our electricity meter. The primary objective of this project is to automate the entire process to make it seamless, convenient, and effective. The software can compute the bill amount on the basis of units of electricity consumed in a month. Electricity Billing System is considered one of the best java project ideas for beginners. The app should have the below-mentioned features:

• Accurately calculate the bill amount.
• Instantaneous sharing of data between local electricity offices and users.
• Extremely safe to negate the chances of tampering.

The undertaking is called a “Virtual Medicine Home.” By using this application, patients can reserve online meetings with their preferred specialists. Specialists can recommend medical services, e-remedy, and consider the patient’s clinical records, lab reports, and many more. The app also lets users explore and interface with individuals who are donating their organs or blood. During the times of the pandemic, when it gets dangerous to visit the hospital, this JAVA project comes to your rescue. The application comes with two modules — an Admin and a Doctor module. The Admin module is responsible for the online programming framework, and the Doctor module allows specialists to communicate with patients.

This venture implies smoothening the inventory network cycle by religiously keeping the sellers and customers in check and always following the items via the different focuses in the inventory network. By using this application, the clients can directly pass on their item prerequisites to the maker, who at that moment reaches various merchants to obtain the basic assets for making the item. Per the items given to them, the vendors as a rule make a rundown of things, post which the maker selects the materials that best serve the particulars provided by the client. The selected rundown of items is sent to the stock division for handling, and then the assembling starts. When the creation is completed, the records office establishes the crude materials’ expenses and the expense of gathering to generate the full bill. Lastly, the item with the receipt is sent to the customer.

This easy java project strives at building an automated seating arrangement of students for exams, on the basis of different inputs.

There are primarily two entities, the admin and the student. Both entities can log in and register to the system, and check and access the system as per the approval granted to them. The admin can see all the relevant details of the students and provide input to the system taking into consideration the need like the branch, semester, year, and subject of the student. Admin will input details like the total number of students, available classes with the number of seats, etc. After gathering all this information the system will generate a seating arrangement based on the row number and the students’ roll number.

This is another Java Project that is very helpful for engineering students to improve their learning in the File and String Handling concepts of Java. The programmer develops an interface on which customers can document their content and then obtain the total words in the content. The programmer strategies and saves the content in a file for the purpose of processing and then processes the content by String class to calculate the words. There are different choices that the programmer creates to make the project more creative and intriguing. You can also employ the Java APIs of formatting to format the content delivered by the client.

This evolved Java project needs refined mastery in Java database connectivity, MySQL, HTTP, and JSpring framework. You ought to learn Spring core/MVC, ORM framework, and Hibernate to accomplish this project. You will develop a management system for the web platform that will let community managers revise and access consumer data for more satisfactory consumer relations. This project utilizes the Spring framework and offers the source sets for Java programming.

If you wish to be an Android developer, incorporating Java Android development application projects into your resume is highly advantageous. This project is an online brain exercise game, which experiments with your memory and cognitive skills. To create this application, you will put up the user interface, implement game logic, make a splash screen, build a game guide, and arrange the game screens. You will also have to develop an APK for the app’s release. The last step includes an automatic data processing scoreboard in the app that keeps a track of the player’s answers.

If you are curious about the system and network administration profession, then this project might benefit you. The objectives of this project are to develop system security rules and put up network packet sniffer analyzer software for the purpose of system monitoring. You will construct a packet sniffer that comprises elements like 24/7 monitoring, solving network problems, packet decoding, protocol analysis, and storing real-time data. It comes with modules like statistics, packet analysis, and a user interface module.

6 Interesting Ideas from Research Papers about Java

There are a lot of research papers related with Java. If we type “Java programming”, there are more than a million result in Google scholar. Some papers are very theoretical, some seem to be practical. I recently found some ideas are pretty interesting, so I collect them and create a list. These papers are from world top software engineering conferences.

1. Automatically Insert Blank Lines to Improve Code Readability

As a coding convention, programmers use blank line to separate different logical sections in a Java method. When a method does not contains blank lines, the technique presented in this paper can insert blank lines.

Paper Link 1 , Paper Link 2

2. Automatically Identify One of the Most Common Idioms – Loops-If

Code idioms are code fragments that recur frequently across software projects and have a single semantic purpose. This paper detect loops that contains a single if, such as the following:

for (Iterator<RepoSource> it=mSources.iterator(); it.hasNext(); ) { RepoSource s=it.next(); if (s.isUserSource()) { it.remove(); } }

Such a structure does 12 common things, such as find an element, count, filter, etc. If the idea is implemented, old version Java might be migrated to Java 8 Stream API automatically.

3. Mine idioms from source code

This paper presents a technique which automatically retrieve all common code idioms. It is interesting to see that one of the most common idioms is:

Document doc=Jsoup.connect(URL). userAgent("Mozilla"). header("Accept","text/html"). get();

Of course, the result depends on what open source projects they use for the mining purpose.

4. Mine Code Examples from Open Source Projects

The technique presented in this paper can recommend code examples based on context. I always hope there is a tool that can recommend the next line based on the code that has already been typed. Hopefully such a tool can come out of research lab soon.

5. Generate Comment for Source Code by Using Stack Overflow

Comments improve program comprehension and software maintainability. It is beneficial to generate code comments automatically. In this paper, they propose a general approach to generate code comments automatically by analyzing existing open source projects and Stack Overflow posts. They discover similar code and use the description on Stack Overflow to describe the other similar code segments.

6. Generate Comment from Source Code

Comments improve program comprehension and software maintainability. This paper summarizes the comment generation work.

Those ideas are pretty cool. Hopefully they can release their implementation soon.

Java Frameworks You Must Know in 2024

Many developers trust Java worldwide because it is adaptable, secure, and versatile, making it perfect for developing various applications across multiple platforms. It also stands out for its readability and scalability.

What are frameworks? Why do you need them?

Since Java has a long history, there are plenty of frameworks and libraries to streamline your Java development process.

They provide pre-made chunks of code and a set of rules on how to build your app. This means you don’t have to start from zero every time you want to create something; you can use these tools to help you along, making it faster and easier to get your app working

In this article, we’ll look at the most popular, efficient, and trending Java frameworks that can help you level up your code.

Spring Framework and Spring Boot

Since the early 2000s, Spring has evolved alongside Java to provide efficient tools for building Java applications for projects ranging from small-scale web apps to large, complex systems. Spring is not just a framework. It’s an entire ecosystem of supporting frameworks and tools that cover almost all aspects of application development and ensure your application can be developed, tested, and scaled efficiently.

Where to Use Spring

You can use Spring in various areas, including web and enterprise development, microservices, data management, cloud-based applications, big data processing, automation, and testing.

Cool Features

Here is a list of the most powerful capabilities that Spring has to offer

Dependency Injection . Spring lets you inject dependencies either through constructors or setters, making your code neater and more organized.

Spring MVC : This is a popular Java framework used for building web applications. It follows the Model-View-Controller (MVC) architectural pattern that separates the application into three main parts: model, view, and controller.

Spring Boot : This is a sub-project of Spring that allows you to create stand-alone, ready-for-production Spring applications with minimal setup and configuration.

Transaction Management : Spring gives you a consistent way to manage transactions across different APIs like JTA, JDBC, Hibernate, JPA, and JDO.

Spring Data : This makes building applications with Spring and data access technologies more efficient.

Spring Security : A powerful framework that provides strong and customizable security measures for your Spring applications, including authentication and access control.

Testing Support : Spring offers great tools for unit and integration testing, including libraries like JUnit, Mockito, and more.

IntelliJ IDEA provides full Spring support . IntelliJ IDEA has Spring Initializr integration which allows you to create a new Spring project in just a few clicks right from the Welcome screen. What’s more, our IDE provides advanced coding assistance for Spring, including navigation, validating configurations, displaying autowired beans, etc.

First Steps

• Getting Started
• Creating a Spring Boot “Hello World” Application with IntelliJ IDEA
• Build a Spring Boot App with AI Assistant

Micronaut 

Micronaut is a JVM-based framework used for developing microservices or serverless applications. It’s designed to provide the tools and infrastructure for building scalable, high-performance applications with minimal memory footprint and startup time. The framework supports the Java, Kotlin, and Groovy languages. Micronaut shares some similarities with frameworks like Spring, yet it stands out for its unique features.

Where to Use Micronaut

It is excellent for developing microservice-based applications and is also useful in cloud environments like Docker and Kubernetes.

Dependency injection happens at compile time instead of runtime, as in most frameworks. This method, unlike the traditional use of reflection and proxies, allows you to start the application faster and reduce memory usage.

Reactive programming support supports reactive programming models, making it easier to handle asynchronous data flows and concurrency.

Extensive integration provides seamless integration with a variety of databases, cloud services, and other tools, offering flexibility in application development.

• Quick Start
• Creating your first Micronaut application
• Developing Micronaut Applications with IntelliJ IDEA
• Introduction to Micronaut

Hibernate is an open-source Object-Relational Mapping (ORM) framework for Java applications. It’s designed to simplify the development of data-driven applications. Hibernate has its own language, Hibernate Query Language (HQL), which uses objects instead of table names. Thanks to HQL, Hibernate can significantly reduce development time, make your code less error-prone, and easier to understand and maintain than raw SQL. 

Where to Use Hibernate

Hibernate can be used in any Java application that interacts with a relational database. 

Cool Features 

Lazy Loading : Your data is retrieved only when called, saving memory and improving performance.

Cache Mechanism : This mechanism allows frequently used data to be stored in memory, which reduces database load and speeds up data retrieval in your application.

Reduced Boilerplate Code : With Hibernate, you don’t have to write tedious JDBC code for CRUD (create, read, update, delete) operations. It manages the database operations in the background, thus reducing your development time.

IntelliJ IDEA offers coding assistance for Hibernate, such as autocompletion for HQL queries, handy inspections and quick-fixes, and the Hibernate console that allows you to run your HQL queries straight from the IDE.

Apache Kafka 

While not a framework, Apache Kafka is an essential open-source stream processing platform for handling large amounts of data in real time. We consider it to be a very helpful asset for Java developers as it can scale up effortlessly without any downtime, making it great for managing big data projects.

Combining the various Kafka APIs for publishing or subscribing to one or more Kafka topics and the Kafka Streams API to implement stream processing gives you a good foundation for building scalable, decoupled applications.

Where to Use Kafka

Kafka is great for handling live data and constantly updating applications. It’s used on websites to track what users are doing and also in systems that need to share data between different parts.

Decoupling : Apache Kafka helps systems and data streams work independently and asynchronously. This can be explained through basic terms. Kafka uses topics to organize data streams. Producers send messages to the topics without needing to know who will consume them and don’t wait for a consumer to be available. Consumers subscribe to topics and handle messages at their own speed without blocking the producer if it’s processing messages slowly.

Fault tolerance in Apache Kafka means that even if something goes wrong, like a server crashing, Kafka can keep running without losing data. It does this by making copies of data and automatically switching to backups if needed.

Integration with other systems : Kafka can integrate with a wide range of systems, including databases, file systems, stream processing frameworks, etc.

IntelliJ IDEA offers the Kafka plugin , which allows you to monitor your Kafka event streaming, make consumers, producers, and topics, and connect to Schema Registry to create and update schemas.

JUnit 5 is a popular Java framework used for writing and running automated tests to check if your code is working as expected. JUnit 5 helps keep your code neat and readable, find and fix errors, boost software quality, and improve testing efficiency.

Where to Use JUnit 5

JUnit is predominantly used for unit testing of individual units of Java code (like methods or classes) in isolation from the rest of the application.

Annotations . JUnit 5 annotations serve as special markers in Java code, offering

instructions to the JUnit 5 framework on test execution. For instance, @Test marks a method as a test method, while @Disabled skips the annotated test method during execution. @DisplayName allows you to write a display name for your test in a normal sentence.

Assertions are the methods that verify that your code behaves as expected.

Test runners are special programs that allow you to run tests and see the results, telling you which tests passed or failed.

Test suites : This feature lets you group several tests and run them together.

Parameterized tests allow you to run the same test multiple times with different sets of parameters, making sure the functionality works for different inputs.

Nested tests : The @Nested annotation in JUnit 5 allows you to group several test methods within nested classes inside a main test class, helping to organize tests more clearly and adding expressiveness to your tests, making them easier to read and understand.

IntelliJ IDEA is fully integrated with the JUnit framework. To create a test for a specific class, you can simply right-click on it, select Create test , and choose JUnit 5 as a desired testing library. Running tests is also straightforward and easily accessible from the UI. It’s that simple!

Mockito 

Mockito is a popular mocking framework for unit tests in Java. It allows you to create mock objects in automated unit tests that mimic the real objects in your tests. For instance, if your code needs to fetch data from a database, Mockito allows you to set up a mock database that returns the required test data, so you don’t have to use the actual database. 

Where to Use Mockito

You can use Mockito in unit tests to isolate code units by mocking their dependencies.

Automated mock creation : You can create mocks with the @Mock annotation to reduce boilerplate code in your tests. 

Spying allows you to use real objects in your tests, calling all their methods except the ones you choose to stub. 

Methods stubbing : Stubs define how a mocked method should behave when invoked. For example, you can make a method return a specific value or throw an error when tested. This helps you check how your code works in different situations without using the actual methods.

ArgumentCaptor lets you capture and examine an argument passed to a method, which is very helpful when the argument isn’t accessible outside the method you’re testing.

WireMock is another framework that can help you create stubs and mocks. However, this time, the framework simulates HTTP-based APIs. It acts as a real web server that is capable of providing stubbed responses to a client’s requests.

Where to Use WireMock

Use WireMock when you want to test your application’s interaction with external HTTP services, during the development of a microservice that depends on other services, or to create detailed logs for debugging complex issues, without having to use those actual services.

Fault Simulation : WireMock allows you to simulate problems such as delays, connection resets, and random noise, mimicking an unreliable server or network. 

Request Matching : It is possible to match incoming requests by URL, HTTP method, headers, and body content to determine the appropriate response.

Record and Playback : It is capable of recording requests to a real service and then playing them back, which is useful for creating mocks based on actual service behavior.

Starting from version 2024.1, IntelliJ IDEA comes with the WireMock plugin.

Testcontainers 

Testcontainers is another framework for testing your application. It focuses on integration testing, which checks how different parts of an application work together. It is designed for situations where you need to write integration tests with other services that should be running during your tests.

Where to Use Testcontainers

Testcontainers is ideal for integration tests and for testing the full flow of an application in an environment that imitates production setup. 

Test isolation guarantees that your tests will not affect each other’s data.

Support for various technologies : Testcontainers supports databases like MySQL, Postgres, MongoDB, and others. It also works with Selenium browser environments for end-to-end tests, and message brokers like RabbitMQ, Kafka, etc.

Easy integration with JUnit allows you to effortlessly add tests that use containers to your current tests. 

Automatic clean-up : Testcontainers removes everything it uses, like containers, volumes, or networks, after the tests are done. This keeps your testing space tidy and helps avoid resource leaks.

You can use Testcontainers in IntelliJ IDEA with your test framework of choice, for example with JUnit.

Awaitility is a small open-source Java DSL library that simplifies testing asynchronous systems. This means that it lets the tests wait until an asynchronous operation finishes or a specific condition is met, which is very helpful for testing concurrent systems.

Where to Use Awaitility

Use Awaitility when writing tests that include asynchronous operations, such as:

• Ensuring actions are completed within a specific time frame.
• Testing web services or similar systems where responses can be delayed.
• Checking conditions in multithreaded or concurrent systems within a defined period.

Timeout: Awaitility allows you to set a timeout for a specific condition in a test. If the condition isn’t met within this time limit, it stops the test, preventing it from running forever.

Custom conditions : Beyond just using timeouts, you can create specific conditions for more flexible testing in various scenarios. 

DSL Syntax : Offers an easy, explicit syntax for specifying conditions, making tests easier to understand and maintain.

Jackson is a comprehensive library for reading, writing, and manipulating JSON data in Java applications. With its help, you can parse JSON to Java objects and serialize Java objects to JSON.

Where to Use Jackson

Jackson is highly versatile and can exchange data over RESTful APIs, persisting Java objects to JSON files, and processing external JSON data. 

Java annotations support : Jackson allows developers to use Java annotations extensively, giving them significant control over the serialization and deserialization processes.

Streaming API : It offers a fast, efficient method to read and write JSON, which is ideal for handling large JSON files or data streams with minimal resource usage.

Support for various data formats : Jackson can work with various data formats such as JSON, XML, CSV, and YAML.
