Answer 1

thanks dwg but i have a little problem here
i have 2 classes one for the systemtray and other for actions on it
each class is independent
      public void setupSystemTray() {
        if (SystemTray.isSupported()) {
            SystemTray tray = SystemTray.getSystemTray();
            Image image = Toolkit.getDefaultToolkit().getImage("D:\\Other\\JAVA\\Icons\\shutdown.png");
             PopupMenu popup = new PopupMenu();         
             MenuItem defaultItem2 = new MenuItem("Restore");
              MenuItem defaultItem = new MenuItem("Exit");
               defaultItem.addActionListener(this);
              popup.add(defaultItem2);
             popup.add(defaultItem);   
            trayIcon = new TrayIcon(image, "JShutdown Timer",popup);
            trayIcon.setImageAutoSize(true);
            trayIcon.addActionListener(new TrayActionListener());
            try {
                tray.add(trayIcon);
            } catch (AWTException e) {
                System.err.println("TrayIcon could not be added.");
                                       class TrayActionListener implements ActionListener {
        public void actionPerformed(ActionEvent e) {
           trayIcon.getPopupMenu();
         if(e.getSource()==defaultItem)
              System.exit(0);
    };and i want if the user chooses the exit menuitem the program exits
so i write
if(e.getSource()==defaultItem)
              System.exit(0);
         }in the second class the IDE didn't recognize the variable defaultItem
and it gave me error couldn't find simple variable
how to fix that?
