请使用准确的文字描述作为标题

原标题 : 菜鸟求助~~~在线等~~急~~~谢谢~!

程序如下:

import java.awt.*;
import javax.swing.*;

import java.awt.event.*;
import MyWindowListener;

public class MyColor2 extends JFrame implements ActionListener
{
private JButton changeColor;
private Color color = Color.lightGray;
private Container c;

public MyColor2()
{
super("MyColor2:使用JColorChooser元件");
c = getContentPane();
c.setLayout(new FlowLayout());
changeColor = new JButton("改变背景颜色");
changeColor.addActionListener(this);
c.add(changeColor);
setSize(300,80);
show();
}
public void actionPerformed(ActionEvent e)
{
color = JColorChooser.showDialog(this,"选色",color);
if(color == null) color = Color.lightGray;
c.setBackground(color);
c.repaint();
}
public static void main(String args[])
{
MyColor2 app = new MyColor2();
app.addWindowListener(new MyWindowListener());
}
}

import MyWindowListener;这里错了~~~请问如何增加这个窗口监听呀?
要对准这行的app.addWindowListener(new MyWindowListener());
请问如何做得到呀?谢谢啦~!有其它方法的也说说吧~尽量详尽点~!谢谢啦~!
