This forum is for Servlets questions, your Java In General question is not about Servlets. Please post your questions in the most appropriate forum.

I will move this thread to the Java In General (Beginner) forum for you.

These sound like Assignment questions. If you can demonstrate some understanding, we can help, but not a full answer which you may pass as your own. But to get you started:

Interfaces - Bare classes with no implementations, just method "headers". Like a contract.

Abstract - Like interfaces, but some implementation may be provided for certain methods. Cannot create instances of Abstract classes.

Now ask yourself which is better and why.
 
Don't get me started about those stupid light bulbs.
