What are characteristic's of Object Oriented System's?

The characteristics of Object Oriented System's are as follows:

1)    Abstraction: The Abstraction allows the complex real world to be represented in simplified manner. For example color is abstracted to RGB. By just making the combination of these 3 colors we can achieve any color in the world. This is a model of real world or concept.

2)    Encapsulation: This is a process of hiding all the internal details of an object from the outside world.

3)    Inheritance: The Hierarchy used to define more specialized classes are based on a preexisting generalized class. For example we have VEHICLE class and we can inherit this class make much specialized class like CAR, which will add new attributes and use some existing features of the parent class. This shows more of a parent-child relationship. This kind of hierarchy is known as inheritance.

4)    Polymorphism: When inheritance is used to extend a normalized class to a more specialized class, it includes the behavior of the top class (Generalized class). The inheriting class sometimes implement the behavior that can be somewhat differ than the normalized class, but the name of the behavior can be similar. It is very important that a given instance of an object use the right behavior, and the property of polymorphism allows this to happen automatically.
