Hi,

Here is the description of Encapsulation in java:

Encapsulation is a process of binding or wrapping the data and the codes that operates on the data into a single entity. This keeps the data safe from outside interface and misuse. One way to think about encapsulation is as a protective wrapper that prevents code and data from being arbitrarily accessed by other code defined outside the wrapper.

In other words, encapsulation is the ability of an object to be a container (or capsule) for related properties (ie. data variables) and methods (ie. functions).


public class Box
{
// what are the properties or fields
private int length;
private int width;
private int height;

// what are the actions or methods
public void setLength(int p)
{length = p;}

public void setWidth(int p)
{width = p;}

public void setHeight(int p)
{height = p;}

public int displayVolume()
{System.out.println(length*width*height)...
}

public static void main(String args [ ])
{
Box b1=new Box(3,4,5);
b1.displayvolume();
}


Thanks
