Empty is abstract classvery similar to interface, except that it can expandclass

abstract class myAbstractClass // extends anotherClass implements anInterface
{

}

interface myInterface // extends anotherInterface
{

}

This template is called the marker interface , and SO has a lot of good data about it already: What is the purpose of the marker interface?
