import java.applet.*;

import java.awt.*;

import java.awt.event.*;

public class Practical4 extends Applet implements MouseMotionListener

{

    static int x,y;

    public void init()

    {

        addMouseMotionListener(this);

    }

    public void paint(Graphics g)

    {

        g.drawString("X=" + x + ", Y=" + y,15, 15);

        g.drawRect(x, y, 10, 10);

    }

    public void mouseMoved(MouseEvent e)

    {

        x=e.getX();

        y=e.getY();

        repaint();

    }

    public void mouseDragged(MouseEvent e)

    {

       x=getX();

       y=getY();

       repaint();

    }    

}
