怎么实现让程序一旦运行就自动，就自动缩小成窗口右下角的小图标啊

自己的程序可以这样写:
import java.awt.AWTException;
import java.awt.Image;
import java.awt.MenuItem;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.Toolkit;
import java.awt.TrayIcon;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.net.URL;
import java.net.URLClassLoader;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class TestSysteTray
{
public static void main(String args[])
{
TrayIcon trayIcon = null;
if (SystemTray.isSupported()) //判断系统是否支持系统托盘
{
SystemTray tray = SystemTray.getSystemTray(); //创建系统托盘
Image image = Toolkit.getDefaultToolkit().getImage("D://My Pictures//bb.gif");//载入图片,这里要写你的图标路径哦
ActionListener listener = new ActionListener() {
public void actionPerformed(ActionEvent e) {
JFrame frame = new JFrame();
frame.setBounds(400,400,200,
