Java - when to use 'this' keyword

Some developers like to always use "this" when referring to an object's methods and properties, even when it isn't needed. Here's a really simple example:

public class Foo {

    private String id;

    public Foo() {
        this.id = "123456789";
    }

}

Is it clearer to always use "this" or only when it is necessary? Are there any cases in which you should always use it?

Answer 1

It make no difference in the generated code. So use is up to company development guidelines or personal preference.

It can help identify what is a member variable and what is not, it also help to use this-> as the ide or editor can do better code completion (depending on the age of the editor).
