anonymous class?

[Aaron Raja]

It is said: Classes defined in methods can be anonymous, in which case they must be instantiated at the same point they are defined. These classes can�t have explicit constructor and may implement interface or extend other classes.
Can you give me simple example please?

class TestClass {
  void method() {
 
    //extending a class...
    MyClass c = new MyClass() {
      //anonymous class definition here,
      //overriding inherited method...
      void meth() {
        System.out.println("In overridden meth of anonymous class.");
      }
    };
    c.meth();
 
    //implementing an interface...
    MyInterface i = new MyInterface () {
      //anonymous class definition here,
      //implementing interface method...
      public void meth() {
        System.out.println("In anonymous implementation of interface.");
      }
    };
    i.meth();
  }
 
  public static void main(String[] args) {
    TestClass test = new TestClass();
    test.method();
  }
}
 
class MyClass {
  void meth() {
    System.out.println("In meth of MyClass.");
  }
}
 
interface MyInterface {
  void meth();
}
