Answer / balbir

encapsulation:wraping of data and method into single unit.
e.g:

public class Test {
private int id;
private int roll;

public void method(int i,int j){
id = i;
roll = j;
System.out.println("===id==="+id);
System.out.println("===roll==="+roll);
}
public static void main(String args[])
{
Test t =new Test();
t.method(100,200);
}
}

in above example privatevariable wrap with public
method,this is encapsulation.

Abstraction:hiding the implementation details from the
external users.
e.g: electric switch board is available for end user
without knowing the implementation details.means end user
not bother about what is the manufactored items inside th
switch board.this is called abstraction.

Answer / malleswari

an entity.Encapsulation is binding properties and operation
to an entity.

Answer / prashant

abstrction in simple language is making complex thing simple
to use by using small and simple controls.
example:- as we know that the car is made up of many
complicated parts.but without bothering the internal details
of car we can drive using accelerator,break and clutch.in
this example accelarator,break and clutch are the small
controls,which makes possible to operate compicated car


encasulation is a method of defining data members and method
together within a class.

Answer / srikanth

Data abstraction is one part of the data
encapsulation....that means data hiding...by achieving data
abstraction by
1)group of similar variables and methods is called
class...so one class variables and methods are hide to
another....
2)by using access specifiers
