Welcome to the forum. :)

First thing is please stop short messaging. It's difficult to get idea what exactly you want to know. And also you have different sub-forums to ask different questions here in the forum.

For the first question. Yes, Java 100% OO. OOP has large number of concepts. Giving an example on that wont be easy at all.

Explaining Interfaces and Abstract classes is not easy on a forum. First read some materials and ask any question if you stuck with.

Well, if you're talking "purist", no it's not as it has primitives and not everything is an Object. But, this question is completely meaningless, as to say something is 100% pure anything, then the "purity" scale needs to be defined first, which there is no OO purity scale.

Java is Object oriented and there are only very few things about it that are not represented by Objects.

Read the replay before commenting. Don't be hurry. I'm not asking anything on my last post. I'm giving simple guides to you. That's it.

An abstract class is needed when you want to include some inherit functionality and not just definitions/declarations.

A class can, however, extend only one class, but can implement multiple interfaces (although it has then implement those methods themselves).

Also, fields defined in an interface are explicitly public static final, where they are not (at least not by default) in an abstract class.

This is only a few of the differences, but should be enough for you currently.

And, please lose the sms speak. It is very irritating. You have an entire keyboard in front of you (not just a number pad), use it.
