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

Question

interface Int {
    public void show();
}

public class Test {     
    public static void main(String[] args) {
        Int t1 = new Int() {
            public void show() {
                System.out.println("message");
            }
        };

        t1.show();
    }
}

Answer 1

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