OOP Definition

Object-oriented programming is based in the principle of recursive design.

1. Everything is an object.

2. Objects perform computation by making requests of each other through the passing of messages.

3. Every object has it's own memory, which consists of other objects.

4. Every object is an instance of a class. A class groups similar objects.

5. The class is the repository for behabior associated with an object.

6. Classes are organized into singly-rooted tree structure, called an inheritance hirearchy.
