adding thread

[amith]

i sincerely apologize for asking this question again and again but i control it i am stuck by this program for past 3 days this time i am sending the .gif file so that u can easily understand what my idea is
here is the code

Code:

import java.util.*;
import java.awt.*;
import javax.swing.*;
class load extends JFrame
{

Image r;
Image b;

int y=329;
int floor=329;
int x=3;
load()
{

super("some name");
r=new ImageIcon("red.png").getImage();
b=new ImageIcon("blue.png").getImage();

getContentPane().add(new display());
setVisible(true);
setSize(175,400);
setResizable(false);
}

class display extends JPanel //implements Runnable
{
//Thread t=new Thread(this);
display()
{
repaint();
}

public void paintComponent(Graphics q)
{
Graphics2D n=(Graphics2D)q;
q.drawImage(r,x,y,this);
}
/*
i just want to place the red image fixed at the bottom
and start new blue image thread i,e
try
{
y=0;
while(y!=floor)
{
y++;
q.drawImage(b,x,y,this);
Thread.sleep(10);
}
}
catch(Exception e)
{
}
*/

}
}
class f
{
public static void main(String args[])
{
new load();
}
}
