How do I put a Java app in the system tray?

Question

I have a little control-panel, just a little application that I made. I would like to minimize/put the control-panel up/down with the systemicons, together with battery life

It's very simple

import java.awt.*;
import java.awt.event.*;
import javax.swing.JOptionPane;

public class SystemTrayDemo{

//start of main method
public static void main(String []args){
    //checking for support
    if(!SystemTray.isSupported()){
        System.out.println("System tray is not supported !!! ");
        return ;
    }
    //get the systemTray of the system
    SystemTray systemTray = SystemTray.getSystemTray();

    //get default toolkit
    //Toolkit toolkit = Toolkit.getDefaultToolkit();
    //get image 
    //Toolkit.getDefaultToolkit().getImage("src/resources/busylogo.jpg");
    Image image = Toolkit.getDefaultToolkit().getImage("src/images/1.gif");

    //popupmenu
    PopupMenu trayPopupMenu = new PopupMenu();

    //1t menuitem for popupmenu
    MenuItem action = new MenuItem("Action");
    action.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            JOptionPane.showMessageDialog(null, "Action Clicked");          
        }
    });     
    trayPopupMenu.add(action);

    //2nd menuitem of popupmenu
    MenuItem close = new MenuItem("Close");
    close.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            System.exit(0);             
        }
    });
    trayPopupMenu.add(close);

    //setting tray icon
    TrayIcon trayIcon = new TrayIcon(image, "SystemTray Demo", trayPopupMenu);
    //adjust to default size as per system recommendation 
    trayIcon.setImageAutoSize(true);

    try{
        systemTray.add(trayIcon);
    }catch(AWTException awtException){
        awtException.printStackTrace();
    }
    System.out.println("end of main");

}//end of main

}//end of class

Set appropriate path for image and then run the program. t.y. :)
