Hi,
Encapsulation: The wrapping up of a data and methods into a
single unit is called Encapsulation. You can achieve
Encapsulation by using private data and public methods look
at the following example for better understanding.
Eg:
public class EcapTest{
public static void main(String args[]){
private int a=22;
private String s="DEVARATHNAM";
private float f=33.24f;

public void displayData(){
// some code
}
public void getData(){
// some code
}
}//main
{//class.

Observe the above program we are combining both data and
methods into a single unit(EcapTest). I hope i met your
needs.
