Aim: write a program in java bean to implement simple properties of a bean.

Program:

package sunw.demo.Box;

import java.awt.*;

public class Box extends Canvas

{

   private int depth,height,width;

    public Box()

     {

        setSize(120,30);

        height=0;

        depth=0;

        width=0;

}

  public int getDepth()

   {

       return depth;

    }

   public void setDepth(int depth)

    {

       this.depth=depth;

    }

   public int getHeight()

   {

       return height;

    }

   public void setHeight(int height)

   {

       this.height=height;

    }

   public int getWidth()

   {

       return width;

    }

   public void setWidth(int width)

    {

        this.width=width;

    }

    public void paint(Graphics g)

    {

        double volume=(height*depth*width);

        String msg="Volume="+volume;

        g.drawString(msg,10,10);

     }

 }

Output:
