Thanks Bear. I'll try the abstract idea, but the private constructor idea can't work. If a subclass extends a superclass, the superclass' constructorwill be called before the subclass'. If the superclass' constructor is private, it will through a compile-time error.

One of the key purposes of making a class abstract is to prevent it from being instantiated. Abstract classes do not have to have abstract methods.
