What is the difference between Class.this and this in Java


java this

In this case, they are the same. The Class.this syntax is useful when you have a non-static nested class that needs to refer to its outer class's instance.

class Person{    String name;    public void setName(String name){        this.name = name;    }    class Displayer {        String getPersonName() {             return Person.this.name;         }    }}

java this

This syntax only becomes relevant when you have nested classes:

class Outer{    String data = "Out!";    public class Inner{        String data = "In!";        public String getOuterData(){            return Outer.this.data; // will return "Out!"        }    }}

java this

You only need to use className.this for inner classes. If you're not using them, don't worry about it.
