I don't believe so. You do not have to implement any of its methods.

Math is just a final class. Not abstract. Not sure why you'd think those other ones are. Remember an abstract class cannot be instantiated (Which those can). You probably create strings all the time. @Josh EventListener is an interface.

I do not believe any of them are. The eventListener class however might be.
