I'm thinking that Marilyn's link isn't pointing where she'd hoped.

Note that the search page link is at the top right of this page.

A single line answer to a question "What is an interface?" would be...an interface defines a set of requirements to which every implementing class should comply. Whereas, Abstract classes factor out common functionalities that are going to be shared by all of its subclasses, but doesn't know the concrete implementations of those functionalities. This will have to be supplied by the extending superclasses. This was just to give you a basic idea of what you mean by Abstract classes and interfaces.

You should definitely do some home work on this.This is where you can start.
