Hi Guys,

I need some help defining some java terms. I've been reading up on them but I still cant get my head around some of them and would like someone to explain it in real simple terms with some examples please.

1. Object
2. reference (e.g. references to objects)
3. instance
4. What is the purpose of an abstract class?
5. container
6. packages test;
7. import test.*;
8. Polymorphism
