what is object oriented ?

 The term ‘object-oriented’ means that we organize software as a collection of discrete objects that incorporate both data structure and behaviour are only loosely connected .

An object oriented approach generally include for aspects: they are :

a)Identity

b)Classification

c)Polymorphism

d)Inheritance

a)Identity:- means that data is quantized into discrete distinguishable entities called objects. A paragraph in a document , a window on my workstation and the white queen in a chess game are examples of objects. Objects can be concrete or conceptual . Two objects are distinct even if all their attributes values are identical.

b) Classification : means that object with the same data structure (attributes) and behavior are grouped in to a class . fruits ,vegetable and furniture’s are example of class. A class is an abstraction that describes properties important  to an application and ignores the rest. Each objects is said to be an instances of its class.

c)Polymorphism:-means that the same operation may behave differently on different classes.

d)Inheritances:- is sharing of attributes and operation among classes based on a hierarchical problems.
