How to hide a JFrame in system tray of taskbar

I have created a JFrame and want to hide it in the taskbar in windows, but, it should not be visible in the bottom right corner, but hidden in the tray menu items.

Can anybody tell me how to do this?
Do I need to make some changes in system settings of windows?

For example, you might have seen some download managers, Team Viewer, 4shared desktop, etc. are hidden in taskbar's tray menu items.

Solution 1:

import java.awt.*;
import java.awt.event.*;
import javax.swing.JFrame;
import javax.swing.UIManager;

public class HideToSystemTray extends JFrame{
    TrayIcon trayIcon;
    SystemTray tray;
    HideToSystemTray(){
        super("SystemTray test");
        System.out.println("creating instance");
        try{
            System.out.println("setting look and feel");
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        }catch(Exception e){
            System.out.println("Unable to set LookAndFeel");
        }
        if(SystemTray.isSupported()){
            System.out.println("system tray supported");
            tray=SystemTray.getSystemTray();

            Image image=Toolkit.getDefaultToolkit().getImage("/media/faisal/DukeImg/Duke256.png");
            ActionListener exitListener=new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    System.out.println("Exiting....");
                    System.exit(0);
                }
            };
            PopupMenu popup=new PopupMenu();
            MenuItem defaultItem=new MenuItem("Exit");
            defaultItem.addActionListener(exitListener);
            popup.add(defaultItem);
            defaultItem=new MenuItem("Open");
            defaultItem.addActionListener(new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    setVisible(true);
                    setExtendedState(JFrame.NORMAL);
                }
            });
            popup.add(defaultItem);
            trayIcon=new TrayIcon(image, "SystemTray Demo", popup);
            trayIcon.setImageAutoSize(true);
        }else{
            System.out.println("system tray not supported");
        }
        addWindowStateListener(new WindowStateListener() {
            public void windowStateChanged(WindowEvent e) {
                if(e.getNewState()==ICONIFIED){
                    try {
                        tray.add(trayIcon);
                        setVisible(false);
                        System.out.println("added to SystemTray");
                    } catch (AWTException ex) {
                        System.out.println("unable to add to tray");
                    }
                }
        if(e.getNewState()==7){
                    try{
            tray.add(trayIcon);
            setVisible(false);
            System.out.println("added to SystemTray");
            }catch(AWTException ex){
            System.out.println("unable to add to system tray");
        }
            }
        if(e.getNewState()==MAXIMIZED_BOTH){
                    tray.remove(trayIcon);
                    setVisible(true);
                    System.out.println("Tray icon removed");
                }
                if(e.getNewState()==NORMAL){
                    tray.remove(trayIcon);
                    setVisible(true);
                    System.out.println("Tray icon removed");
                }
            }
        });
        setIconImage(Toolkit.getDefaultToolkit().getImage("Duke256.png"));

        setVisible(true);
        setSize(300, 200);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
    public static void main(String[] args){
        new HideToSystemTray();
    }
}

This is the working program!

Solution 2:

myFrame#getExtendedState and myFrame#setExtendedState

basically is better to multiplay these ExtendedStates

frame.setExtendedState(JFrame.ICONIFIED);
frame.setExtendedState(frame.getExtendedState() | JFrame.ICONIFIED);


frame.setExtendedState(JFrame.NORMAL);
frame.setExtendedState(frame.getExtendedState() & (~JFrame.ICONIFIED));

EDIT 1.

for example

import java.awt.event.ActionEvent;
import javax.swing.*;  
public class WindowGCDemo1 {  
    private javax.swing.Timer timer = null;
    private int count = 0;
    private JFrame myFrame = new JFrame();  
    public WindowGCDemo1() {
        myFrame = new JFrame();
        myFrame.setLocation(150, 150);
        myFrame.setSize(200, 400);
        myFrame.setVisible(true);
        System.out.println(myFrame.getExtendedState());
        start();
    }  
    private void start() {
        timer = new javax.swing.Timer(1000, updateCol());
        timer.start();
    }  
    public Action updateCol() {
        return new AbstractAction("Set Delay") {  
            private static final long serialVersionUID = 1L;  
            @Override
            public void actionPerformed(ActionEvent e) {
                timer.stop();
                myFrame.setExtendedState(JFrame.ICONIFIED);
                System.out.println(myFrame.getExtendedState());
                count++;
                startAgain();
            }
        };
    }  
    private void startAgain() {
        timer = new javax.swing.Timer(1000, updateColAgain());
        timer.start();
    }  
    public Action updateColAgain() {
        return new AbstractAction("Set Delay") {  
            private static final long serialVersionUID = 1L;  
            @Override
            public void actionPerformed(ActionEvent e) {
                timer.stop();
                myFrame.setExtendedState(JFrame.NORMAL);
                System.out.println(myFrame.getExtendedState());
                count++;
                if (count > 5) {
                    timer.stop();
                    stop();
                }
                start();
            }
        };
    }  
    private void stop() {
        System.out.println("--------------------------------------------");
        System.out.println("System Exit");
        System.exit(0);
    } 
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {  
            @Override
            public void run() {
                WindowGCDemo1 windowGCDemo = new WindowGCDemo1();
            }
        });
    }
}

EDIT 2.

for SystemTry you have to set for your JFrame#setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE); and in the proper JMenuItem(s) from JPopupMenu, just JFrame#setVisible(true);
