Animal is a user defined class here. 

Animal D = new Animal("Leo") {

        @Override public void makeNoise() {

              System.out.println("Roar!");

       }

};   D.makeNoise();

Its called an anonymous class and used to define the class and any overridden methods at the same time.

  • There is an extension of this for Single-Method-Interfaces now that is even more concise (probably does not apply here, but good to know if you use Java8). – Thilo Mar 02 '15 at 00:11
  • " define the class": Where "class" is a *subclass* of the class (or interface) named by `new`. So it does not instantiate `Animal` here, but an anonymous subclass instance. – Thilo Mar 02 '15 at 00:14

That is an anonymous class. For details about anonymous classes and why they are useful, see this tutorial on anonymous classes.

This is used to override the initial 

Animal.makeNoise()

method with a custom one for just this instance.
