Implementing Generic Interface in Java

Question

I have a Java generics question I was hoping someone could answer. Consider the following code:

public interface Event{}
public class AddressChanged implemen         


        

Answer 1

No, because different "concrete" generic types in Java compile to the same type. The actual interface your object will implement is:

public interface Handles {
    public void handle(Event event);
}

And, obviously, you can't have two different methods with an identical signature...
