In addition to other answers. This kind of anonymous classes are very useful when you’re implementing interface or extending abstract class. For instance:

public interface MyInterface {
    public void doStuff();
}

And here is your implementation:

MyInterface myInterface = new MyInterface() {

    public void doStuff() {
        //here is your implementation
    }

    public void doAnotherStuff() {
        //Note that this method is public, but
        //you're still not able to call it from outside of this class
        //because it's not part of MyInterface's contract
    }
};

This line will give you an error:

myInterface.doAnotherStuff(); //WTF? I don't know about this method of MyInterface
