ENCAPSULATION-> 
* It is a mechanism which unites the code and the data it 
manipulates.

*It keeps them safe from external interference and misuse, 
thus enforcing the separation between specification and 
implementation of ADTs. Hence it enables the debugging of 
program easily.

DATA ABSTRACTION->
* It is the creation of new data types [ADTs] using 
encapsualted-items that are well suited to an application 
to be programmed.

* It is a powerful technique resulting in optimal, more 
readable and flexibles programs.


*******U r most welcome to challenge with my answer*****

(1)Abstraction:
To implement real world entity into program. Class uses the 
concept of abstraction.
->abstraction is a process of mimicking a behavior.
->Simplifying complex reality by modeling classes 
appropriate to problem.
->Abstraction is a process that involves identifying the 
crucial behavior of an object and eliminating irrelevant 
and tedious details. 


(2)Encapsulation:
->Binding the data and code to access that data. 
Encapsulation only refers to a container which has a data 
and its related functions in it.
->When an objects state and behavior are kept together they 
are encapsulated. The data and the methods that manipulated 
that data are stored together in cohesive unit.
