Drawing rectangles in Applet

Question

Hi all.
I am looking to manipulate this code so that the user can draw rectangles rather than dragging dots to the screen.
any ideas how I would do this?
import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
public class L10DragMouse extends Applet {
     private int xValue = -10, yValue = -10;
     public void init()
          addMouseMotionListener(new MotionHandler(this) );
     public void paint( Graphics g )
          g.drawString("Drag the mouse to draw", 10, 20);
          g.fillOval(xValue, yValue, 4, 4);
     public void update(Graphics g) {paint(g); }
     public void setCoordinates(int x, int y)
          xValue = x;
          yValue = y;
          repaint();
class MotionHandler extends MouseMotionAdapter {
     private L10DragMouse dragger;
     public MotionHandler(L10DragMouse d) {dragger = d;}
     public void mouseDragged( MouseEvent e )
          { dragger.setCoordinates(e.getX(), e.getY() ); }
}

Answer 1

Okay it is compiling for me now but is not allowing me to create rectangles when the applet opens up. Just a plain page and no graph / rectangle when I drag mouse.
any ideas?
import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
public class L10DragMouse extends Applet {
     private int xValue = -10, yValue = -10;
        private int origX = -10, origY = -10;
     public void init()
          addMouseMotionListener(new MotionHandler(this) );
     public void paint( Graphics g )
          g.drawString("Drag the mouse to draw", 10, 20);
          g.fillRect(xValue, yValue, origX, origY);
     public void update(Graphics g) {paint(g); }
     public void setCoordinates(int x, int y)
          xValue = x;
          yValue = y;
          repaint();
        public void setOriginalCoordinates(int x, int y)
            origX = -10;
            origY = -10;
class MotionHandler extends MouseMotionAdapter {
     private L10DragMouse dragger;
     public MotionHandler(L10DragMouse d) {dragger = d;}
     public void mouseDragged( MouseEvent e )
          { dragger.setCoordinates(e.getX(), e.getY() ); }
        public void mousePressed( MouseEvent e )
                { dragger.setOriginalCoordinates(e.getX(), e.getY() );}
}
