Help with pop-up menu --- please!

Question

I want to see if I can get this simple code working so that I can integrate the ideas into a larger application. But, I'm getting errors on this one! What am I missing or forgetting?
public class example implements MouseInputListener,MouseMotionListener{
     JPopupMenu menu = new JPopupMenu();
     public static void main (String args[]) {
          Frame f = new Frame();
          {Window w = new Window(f);
          w.setSize(200,100);
          w.setVisible(true);
          w.setLocation(300,300);
          //New Red Window
          {Window w= new warningwindow (f);
          w.setSize(200,100);     //setSize is in a superclass
          w.setVisible(true);
          w.setLocation(370,370);}
          // Create and add a menu item
     JMenuItem item = new JMenuItem("Hi Kimberly!");
     addMouseListener(this); //ERROR WITH THIS LINE
     menu.add(item); //ERROR WITH THIS LINE ALSO
     // Set the component to show the popup menu
     public void mouseClicked (MouseEvent e) {
          if(e.isPopupTrigger()){
               menu.show(e.getComponent(),e.getX(), e.getY());
     public void mouseReleased (MouseEvent e){
          if (e.isPopupTrigger()){
               menu.show(e.getComponent(),e.getX(),e.getY());
     public void mouseExited (MouseEvent e){
     public void mouseMoved (MouseEvent e){
     public void mouseDragged (MouseEvent e){
     public void mousePressed (MouseEvent e){
     public void mouseEntered (MouseEvent e){
}
