How to hide a JFrame in system tray of taskbar

Question

I\'d created a JFrame and want to hide in taskbar (in windows not visible right in the bottom but hidden in the tray menu items<

Answer 1

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);
