Practical 4:Develop an applet that display the position of the mouse at the upper left corder of the appletwhen it is drag or move.Draw a 10*10 pixel rectangle filed with black at the current mouse position.

Code:

import java.applet.Applet;
import java.awt.Frame;
import java.awt.Graphics;
import java.awt.Label;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.MouseMotionListener;


public class Drag extends Applet implements MouseListener,MouseMotionListener  {

String msg="";

int x,y;
public void init()
{
super.init();
setSize(400,400);
addMouseListener(this);
addMouseMotionListener(this);
        }

  public void paint(Graphics s)
{

showStatus(msg);
s.fillRect(x, y, 10, 10);
s.drawString("x: "+x+" Y:"+y, 20,20);
}

@Override
public void mouseDragged(MouseEvent e) {
// TODO Auto-generated method stub
x=e.getX();
            y=e.getY();
msg="X="+x+"Y="+y;
repaint();

}

@Override
public void mouseMoved(MouseEvent e) {
// TODO Auto-generated method stub

x=e.getX();
    y=e.getY();

repaint();
msg="X="+x+"Y="+y;



}

@Override
public void mouseClicked(MouseEvent arg0) {
// TODO Auto-generated method stub

}

@Override
public void mouseEntered(MouseEvent arg0) {
// TODO Auto-generated method stub

}

@Override
public void mouseExited(MouseEvent arg0) {
// TODO Auto-generated method stub

}

@Override
public void mousePressed(MouseEvent arg0) {
// TODO Auto-generated method stub

}

@Override
public void mouseReleased(MouseEvent arg0) {
// TODO Auto-generated method stub

}


}

Output:

Thanks 

Happy Coding ;)
