This appears to create an object from an interface; how does it work?

Question

interface Int {
   public void show();
}

Int t1 = new Int() {
   public void show() {
      System.out.println("message");
}

to.show();

Answer 1

You're defining an anonymous class that implements the interface Int, and immediately creating an object of type thatAnonymousClassYouJustMade.
