Problem with Applet

[tomjrmkay]

hi i have written a java applet just for messing around with because its my first one and i have a question. this is my code:

import java.applet.*;
import java.awt.*;
import java.awt.event.*;

public class Keyboard1 extends Applet
   implements KeyListener, MouseListener {

   int width, height;
   int x, y, ex, ey;
   String s = "";
   String enter = "Mouse is NOT in the applet.";
// Color changing buttons

   CheckboxGroup radioGroup;
   Checkbox radio1;
   Checkbox radio2;
   Checkbox radio3;

// End Color changing buttons

   public void init() {
      width = getSize().width;
      height = getSize().height;
      setBackground( Color.gray );

      x = width/2;
      y = height/2;

      addKeyListener( this );
      addMouseListener( this );

// Color changing buttons

setLayout(new FlowLayout());
radioGroup = new CheckboxGroup();
radio1 = new Checkbox("Red",radioGroup,false);
radio2 = new Checkbox("Green",radioGroup,true);
radio3 = new Checkbox("Blue",radioGroup,false);
add(radio1);
add(radio2);
add(radio3);

//End Color chaning buttons
   }

   public void keyPressed( KeyEvent e ) { }
   public void keyReleased( KeyEvent e ) { }
   public void keyTyped( KeyEvent e ) {
      char c = e.getKeyChar();
      if ( c != KeyEvent.CHAR_UNDEFINED ) {
         s = s + c;
         repaint();
         e.consume();
      }
   }

   public void mouseEntered( MouseEvent e ) {
      enter = "Mouse IS in the applet.";
      repaint();
      e.consume();
   }
   public void mouseExited( MouseEvent e ) {
      enter = "Mouse is NOT in the applet.";
      repaint();
      e.consume();
   }
   public void mouseMoved( MouseEvent e ) {  // called during motion when no buttons are down
      ex = e.getX();
      ey = e.getY();
      repaint();
      e.consume();
   }
   public void mouseDragged( MouseEvent e ) {  // called during motion with buttons down
   }
   public void mousePressed( MouseEvent e ) { }
   public void mouseReleased( MouseEvent e ) { }
   public void mouseClicked( MouseEvent e ) {
      x = e.getX();
      y = e.getY();
      s = "";
      repaint();
      e.consume();
   }

   public void paint( Graphics g ) {
      g.setColor( Color.magenta );
      g.drawLine( x, y, x, y-10 );
      g.drawLine( x, y, x+10, y );
if (radio1.getState()) {
g.setColor( Color.red );
} else if (radio2.getState()) {
g.setColor( Color.green ); 
} else {
g.setColor( Color.blue );
}
      g.drawString( s, x+10, y-3 );
      g.setColor( Color.cyan );
      g.drawString( enter, 10, 25 );
      g.setColor( Color.red );
      g.drawString( "Click where you want to type then type something.", 10, 10 );
      g.setColor( Color.yellow );
      g.drawString( "Your Coords: ("+x+", "+y+")", 10, 40 );
   }
}

When i try to change the color it doesnt work. nothing shows up. it worked fine before i added the changing colors so if anyone knows please reply. thanks.

hi,

i think checkbox objects should add Mouse Listener
