Can an interface be implemented by an annonymous inner class?

[Vishal Saxena]

Extending is very common - like below:

//An example of using an anonymous inner class.
public class MyClass extends Applet {
    ...
someObject.addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent e) {
        ...//Event listener implementation goes here...
            }
});
    ...
    }
}

How about implementing?

Should be easy enough to try. Say, use MouseListener where you are now using MouseAdapter. Let us know the results!

Joe Ess, you are quite right. The commonly used anonymous inner class when one adds an ActionListener is an example of that usage.

I think Joe was hoping for the lightbulb to go on over the head of the original poster... Teach a man to fish and all that...
