import java.awt.*;
import java.awt.event.*;
public class MyFrame
{ public static void main(String args[])
{

Frame f=new Frame("mybole");
f.setSize(600,400);
f.setLocation(100,100);
f.setBackground(Color.blue);
//f.setLayout(new BorderLayout(10,10));
//f.setLayout(new FlowLayout(FlowLayout.LEFT));
f.setLayout(new GridLayout(3,2,10,10));
Button btn1=new Button("sunxin");
Button btn2=new Button("weixin");
Button btn3=new Button("WEST");
Button btn4=new Button("EAST");
Button btn5=new Button("CENTER");
f.add(btn1,"North");
f.add(btn2,"South");
f.add(btn3,"West");
f.add(btn4,"East");
f.add(btn5,"Center");
f.addWindowListener(new MywindowListener());
f.show();

}
class MywindowListener implements WindowListener
{
public void WindowOpened(WindowEvent e)
{

}
public void WindowClosing(WindowEvent e)
{
System.exit(0);

public void WindowIconified(WindowEvent e)
{

public void WindowDeiconified(WindowEvent e)
{

}
public void WindowActivated(WindowEvent e)
{

}
public void WindowDeactivated(WindowEvent e)
{

}
public void windowActivated(WindowEvent e) {
// TODO Auto-generated method stub

直接写个内部类就好了，还写这么麻烦~

Answer 3

其实你要关闭窗口可以直接写一条语句就可以了
那就是：this.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
