               Anonymous class or 
               Anonymous-Inherited class or what??? 
            */
            X xInstance = new X(){

               @Override
           开发者_开发百科    void method1()
               {
                    System.out.println("What kinda class is this ?");
               }   
            }
     }

}

It's an anonymous inner (or nested) class.

Reference: Local and Anonymous Inner Classes

 X xInstance = new X(){

               @Override
               void method1()
               {
                    System.out.println("What kinda class is this ?");
               }   
            }
     }

It is anonymous class. you have overriden implementation of method1()
