-Encapsulation is wrapping of data(Data members) and
associated methods(member functions) into a single unit in
such a way that data can be accessed with the help of
associated methods.
--In a class we can specify the variables(Data members) as
private. So for other classes it will not be accessible.
--Through methods(member functions) only we can access the
member variables or modify them.
--It gives more security for our data. It is nothing but
data hiding.

Answer / bln

Encapsulation is process binding data with an object.
Object consists data and methods, where methods helps to
extract or set data.

All classes developed using OOPS concepts follow the
encapsulation.

Answer / rajasekhar

It is the ability of an object to hide its data and methods
from the rest of the world.

A Class may contains a few members in the form of
properties,events,fields or methods.These members of the
class are not exposed to the outer world directly.Rather
they are ENCAPSULATED by the Class.

Public Class Calculations
{
Private void fnMultiply(int x, int y)
{
return x*y;
}
}

Calculations Obj;
int Result;
Result = Obj.fnMultiply(5,10);

Answer / srinu

Encapsulation=DataHidding+Abstraction is called
Encapsulation is called Encapsulation

EX:-
public class A
{
private String name;
private int age;
publiic setName(String name)
{
this.name=name;
}
public String getName()
{
return name;
}
public setAge(int age)
{
this.age=age;
}
public int age()
{
return age;
}
}

Answer / srinivasa

All the javabeans written in java follows encapsulation.
In java bean variables are declared as private for
security. will be accessed using setter and getter method.

Answer / anjani kumar jha

Binding the Function with its associated data together is
called encapsulation(Tough definition but here is example also)

Think this senario
public class Anjani{
public int size;
public int weight;
...
}
public class Jha {
public static void main (String [] args) {
Anjani a = new Anjani();
a.size = -5; // Legal but bad!!
}
}

if somebody change ur size from -5 to -10; so sad ..........
And now you're in trouble. How are you going to change the
class in a way that
lets you handle the issues that come up when somebody
changes the size variable
to a value that causes problems? Your only choice is to go
back in and write method
code for adjusting size (a setSize(int a) method, for
example), and then
protect the size variable with, say, a private access
modifier. But as soon as you
make that change to your code, you break everyone else's!

The ability to make changes in your implementation code
without breaking the
code of others who use your code is a key benefit of
encapsulation.

Now how u will do this............

Keep instance variables protected (with an access modifier,
often private).
and Make public accessor methods, and force calling code to
use those methods
rather than directly accessing the instance variable.
and For the methods, use the JavaBeans naming convention of
set<someProperty> and get<someProperty>.


so how u will write the code........

full code of incapsulation

class Anjani{
private int size;
public int setSize(int size)
{
this.size=size;

return size;

}
public int getSize()
{
this.size=size;
return size;
}

}
public class jha {
public static void main (String [] args) {
Anjani a = new Anjani();
int x=a.getSize();
a.setSize(10);
System.out.println(a.setSize(10));
}
}
