Mainly there are four concepts for object orientation:
1.Abstraction -grouping of data and behaviour(operations)
into a conceptual object.
2.Encapsulation -Its the implementation mode of data
abstraction.With encapsulation, we can accomplish data
hiding
3.Polymorphism -Polymorphism refers to the process whereby
an object invokes a method of another object in a common
manner (with the same name) without understanding or caring
how it is accomplished.

4.Inheritance-When an object is derived from another
object. It inherits all the properties of another objects.

The core object-oriented concepts and most widely accepted are listed:
Encapsulation
Inheritance
Polymorphism

Encapsulation binds data and methods to a single entity.

Inheritance is a mechanism which allows all the characteristics of a base class to be passed on to a derived class. The mechanism extends an existing base class without modifying it, thus producing hierarchical relationships between them. Inheritance supports substitutability of functions seen in a base class by the derived class so as to extend functionality.

Polymorphism is a mechanism where the definition of a function is bound to a function name depending on data type. The data type may refer to an object pointer or the data type of function parameters.
