Which interface? You forgot to post the name of the interface.

Comparable interface. sr :D

What's wrong with using the Comparable interface?

Have you read the tutorial about interfaces?

I think that it’s possible, because Instead of setting the method compareTo of compareable interface, we can create comparable method in a class. right?

How do you tell a method that wants a Comparable object what it it getting?
