Illegal assignment from list to list exception in salesforce.
We cannot create a class with the names Account, Contact, Opportunity, etc. These are Standard object names. They are reserved keywords in Salesforce. So, you cannot use reserved keywords for your class names.
Change the Class name to resolve this issue.
Sample Code for this Exception:
Illegal assignment from List<Contact> to List<Contact>

Sharing my it experience, using aggregateresult in salesforce.
The aggregate functions COUNT(fieldname) , COUNT_DISTINCT() , SUM() , AVG() , MIN() and MAX() in SOQL return an AggregateResult object or a List of AggregateResult objects. We can use aggregate functions result in apex by using AggregateResult object.
Here is an example to use AggregateResult in Salesforce. In below example I’m using COUNT(fieldname) aggregate function in SOQL to show Account record respective number of Contacts.

AggregateResult
Results are returned in AggregateResult only if a query() or queryMore() call includes the aggregate function. If the call doesn't contain an aggregate function, the results are returned in the QueryResult SObject.
For example, this query returns an array of Contact records in the records field.
When a SOQL query contains an aggregate function , the record field returns an array of AggregateResult records. .
Each AggregateResult object contains a separate field for each item in the SELECT list. For the Enterprise WSDL, retrieve the result for each item by calling getField() on an AggregateResult object when using WSC client framework. For the Partner WSDL, retrieve the result for each item by calling getField() on an object.

金額の集計 (SUM) をしたいのですが、どうしたらいいですか？
金額の合計をしようとして、下記のコードを書きましたが、エラーになります。 コード TotalCharges__c = [SELECT sum(EntryCharge__c) FROM AllocationTable__c WHERE id=:id]; TotalCharges__c ： 通貨 EntryCharge__c ： 数 式（通貨） エラー Save error: Illegal assignment from LIST<AggregateResult> to Decimal CalculateCharge.trigger
集計関数を利用する場合には AggregateResult 型を利用します。また集計結果のデータを直接 Decimal 型の変数に格納することはできない為、各型の valueof メソッドを使用し、型変換を行う必要があります。 具体的には下記サンプルを参照してください。
******************************* AggregateResult ar = [SELECT sum(EntryCharge__c) s FROM AllocationTable__c WHERE id=:id]; TotalCharges__c = decimal.Valueof(string.valueof(ar.get('s'))); system.debug('data = '+String.valueof(j.TotalCharges__c)); *******************************
また、String の型変換メソッドについては こちら を参照してください。

Since Apex is a case-insensitive language, the compiler sees this as the same as the built-in class AggregateResult. The SOQL query is known to return a List<AggregateResult>, as in the built-in class, but your local variable results is being read as a List<Aggregateresult>, as in the class you're writing here. Since those are different types ...

AggregateResult is a read-only sObject and is only used for query results. Aggregate functions become a more powerful tool to generate reports when you use them with a GROUP BY clause. For example, you could find the average Amount for all your opportunities by campaign. AggregateResult[] groupedResults. = [SELECT CampaignId, AVG(Amount) FROM ...
You can also do something like the following. You'd replace your last line with this code: Map<Id, Case> casesById = new Map<Id, Case>([SELECT Id, Subject FROM Case]); List<Id> casIds = new List<Id>(casesById.keySet()); This would get you a Map of the Cases, keyed on their Id as well as a List of the Case Ids. If you can work with a Set, rather ...
Change the Class name to resolve this issue. Sample Code for this Exception: public static List<Contact> contactlist(){. List<Contact> con = new List<Contact>(); con = [ SELECT Id, Email, Name FROM Contact LIMIT 5 ]; return con; Exception: Illegal assignment from List<Contact> to List<Contact>. Another situation when trying to update Trigger:
The issue is that you're using SUM function, this can only be used with Aggregated Queries. If so you should probably GROUP BY result by some field and change return type of the method to List<AggregateResult>.. If you want just a normal query then remove SUM from SELECT.SUM from SELECT.

Save error: Illegal assignment from LIST<AggregateResult> to Decimal CalculateCharge.trigger. Resolution. To use an aggregation function, use the AggregateResult type. In addition, it is necessary to use valueof method for each type to convert the type, because the aggregation result data cannot be stored to a Decimal variable directly.
AggregateResult. A read-only SObject that returns query results only if a query call contains an aggregate function, such as MAX (). Results are returned in AggregateResult only if a query () or queryMore () call includes the aggregate function. If the call doesn't contain an aggregate function, the results are returned in the QueryResult SObject.
0. You can't assign, the types are incompatible. You can use the map constructor that takes a list as argument. Map<Id, Account> myMap = new Map<Id, Account>([SELECT Id, Name FROM Account LIMIT 10]); or if you have existing map - you can call putAll on it. Map<Id, Account> myMap = new Map<Id, Account>(); // some other code, maybe even adding ...
