Windows最小化拖盘其实就是将程序放到托盘里面，需要的时候再点击托盘里面的应用图标，此时就可以正常使用应用了，托盘如下：

下面是一个简单的Java程序，可以把窗口最小化到系统托盘：

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;public class TrayIconDemo {private static void createAndShowGUI() {// 检查系统是否支持托盘if (!SystemTray.isSupported()) {System.out.println("SystemTray is not supported");return;}final PopupMenu popup = new PopupMenu();final TrayIcon trayIcon =new TrayIcon(createImage("icon.png", "tray icon"));final SystemTray tray = SystemTray.getSystemTray();// 添加一个打开菜单项
