Concept name required

I can't remember the name of this concept.

  public interface MainInterface {
      public void method1();
      public void method2();
 }

  void testMethod() {
        methodMain(new MainInterface() {

            @Override
            public void method1() {
                System.out.println("This is method1");
            }

            @Override
            public void method2() {
                System.out.println("This is method2");
            }
        });
    }

   void methodMain(MainInterface mi) {
        mi.method1();
        mi.method2();
   }

What is this concept and how exactly it works?

The concept is referred to as callback. In java, you only have callback interfaces, in other languages you can have callback functions.

As a design pattern, this concept is involved in the strategy pattern (as amit already mentioned).

You have created an instance of an Anonymous Inner Class (i.e. a class without a name).
