Introduction
Object Orientation has become more and more important in the last years. Object oriented programming was designed for re-use of codes. It is a type of programming in which programmers define not only the data structure, but also the types of operations that can be applied to the data structure. In this way, the data structure becomes an object that includes both data and functions. In addition, programmers can create relationships between one object and another. For example, objects can inherit characteristics from other objects. One of the principal advantages of object-oriented programming techniques over procedural programming techniques is that they enable programmers to create modules that do not need to be changed when a new type of object is added. A programmer can simply create a new object that inherits many of its features from existing objects. This makes object-oriented programs easier to modify.

Object oriented language uses the following concepts
Classes, Objects, Instance variables and Methods.
Basically everything in object orientation is considered an object, except for the primitive data types: There are mainly three groups of primitive data types: numeric types, Boolean types and arrays. Objects contain attributes and methods.
The attributes of an object are just like Adjectives in the English language. The attributes describe the objects like adjectives describe the nouns. A class is determined by common attributes, all objects falling under this category of common attribute belong to that class.
Methods are like verbs, they describe the action or task performed by the object Since objects are the fundamental building blocks they can inherit attributes and methods from their parent class. Objects can also collaborate with each other.

Inter-phases
Objects can have: public interphase, private interphase.

Inheritance
If there is already a class which can respond to a bunch of different messages, and if you wanted to make a new, similar class which adds just a couple of more messages you do not have to re-write the entire class. All you need to do is create a subclass of the original class. This new class inherits all the existing messages, and therefore, all the behavior of the original class. The original class is called the parent class, or superclass, of the new class. Some more jargon-- a subclass is said to be a specialization of its superclass, and the conversely a superclass a generalization of its subclasses. ...
