As per specification, assignment returns value of the left-hand side (the variable that was assigned to).
The if-then and if-then-else Statements (The Java™ Tutorials
The Java Tutorials have been written for JDK 8. Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available.
Java if...else (With Examples)
The Java if...else statement is used to run a block of code under a certain condition and another block of code under another condition. In this tutorial, we will learn about if...else statements in Java with the help of examples.
Java If ... Else
Learn how to use java if else statements to control the flow of your program. W3Schools provides examples and exercises to practice.
Java if statement with Examples
The code above demonstrates how to use an if-else statement in Java with Boolean values. The code starts with the declaration of two Boolean variables a and b, with a set to true and b set to false. The first if-else statement checks the value of a.
Mastering If Statements in Java: Basics and Beyond
This guide will walk you through the ins and outs of using if statements in Java, from the basics to more advanced techniques. We'll cover everything from the syntax of if statements, how to use them in different scenarios, to common pitfalls and how to avoid them.
If, If..else Statement in Java with Examples
In this case we have two print statements in the program, but only one print statement executes at a time based on the input value. We will see how to write such type of conditions in the java program using control statements.
Java Assignment Operators with Examples
2. Compound Assignment Operator: The Compound Operator is used where +,-,*, and / is used along with the = operator. Let's look at each of the assignment operators and how they operate: 1. (=) operator: This is the most straightforward assignment operator, which is used to assign the value on the right to the variable on the left.
Assign variable in if condition statement, good practice or not?
Assignment in a conditional statement is valid in javascript, because your just asking "if assignment is valid, do something which possibly includes the result of the assignment". But indeed, assigning before the conditional is also valid, not too verbose, and more commonly used. - okdewit.
1.4. Expressions and Assignment Statements
In this lesson, you will learn about assignment statements and expressions that contain math operators and variables. 1.4.1. Assignment Statements ¶. Remember that a variable holds a value that can change or vary. Assignment statements initialize or change the value stored in a variable using the assignment operator =.
Java if-else
Java if-else. Decision-making in Java helps to write decision-driven statements and execute a particular set of code based on certain conditions. The if statement alone tells us that if a condition is true it will execute a block of statements and if the condition is false it won't. In this article, we will learn about Java if-else.
Programming via Java: Conditional execution
Programming via Java: Conditional execution. Chapter 7. Conditional execution. Recall our MovingBall program of Figure 6.3, in which a red ball moved steadily down and to the right, eventually moving off the screen. Suppose that instead we want the ball to bounce when it reaches the window's edge.
Assignment, Arithmetic, and Unary Operators (The Java™ Tutorials
The Java programming language provides operators that perform addition, subtraction, multiplication, and division. There's a good chance you'll recognize them by their counterparts in basic mathematics.
Java 8
Assignment Operators Overview Top. The single equal sign = is used for assignment in Java and we have been using this throughout the lessons so far. This operator is fairly self explanatory and takes the form variable = expression; . A point to note here is that the type of variable must be compatible with the type of expression.
Equality, Relational, and Conditional Operators (The Java™ Tutorials
The Java Tutorials have been written for JDK 8. Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available.
java
The rule is not that "assignment can't be used in an if statement", but that "the condition in an if statement must be of type boolean ". An assignment expression produces a value of the type being assigned, so Java only permits assignment in an if statement if you're assigning a boolean value.

Java conditional checks and assignment
I think the OP wants to avoid the variable assignment when the method returns null. Of course, if he's actually doing System.exit(0) it won't matter.
Assignment Operator in Java with Example
The = operator in java is known as assignment or simple assignment operator. It assigns the value on its right side to the operand (variable) on its left side. For example : a = 20; // variable a is reassigned with value 20. The left-hand side of an assignment operator must be a variable while the right side of it should be a value which can be ...

Why would you use an assignment in a condition?
That warning is not because there is anything wrong with an assignment in a while, but because doing an assignment when you really meant to do a comparison is a common bug. If you want to get rid of the warning you can do the JS equivalent of what @Jonathan Leffler suggests.
