Application of the core logic, hidden to the tray is the essence of the hidden form. That is, setVisible(false), the display of the form is that setVisible(true).

The project code is as follows:

package org.pdp.frame;

 import java.awt.AWTException;
 import java.awt.MenuItem;
 import java.awt.PopupMenu;
 import java.awt.SystemTray;

 import javax.swing.JMenuItem;

         this.jmenuBar.add(menu);
     }

             ImageIcon icon = new ImageIcon(resource); //Create a picture object
