大家帮忙看看这段代码错在哪？
import java.awt.*;
import java.awt.event.*;
public class FrameTest {
public static void main(String[] args) {
Frame f = new Frame();
f.setSize(600,400);
f.setLocation(100,100);
Button btn1 = new Button("北");
Button btn2 = new Button("南");
Button btn3 = new Button("西");
Button btn4 = new Button("东");
Button btn5 = new Button("中间");
f.setLayout(new BorderLayout(10,10));
f.add(btn1,"North");
f.add(btn2,"South");
f.add(btn3,"West");
f.add(btn4,"East");
f.add(btn5,"Center");
f.setBackground(Color.BLUE);
f.setVisible(true);
f.addWindowListener(new MyWindowListener());
}
}
class MyWindowListener implements WindowListener {
void windowOpened(WindowEvent e) {
}
void windowClosing(WindowEvent e) {
System.exit(0);
}
void windowClosed(WindowEvent e) {
}
void windowIconified(WindowEvent e) {
}
void windowDeiconified(WindowEvent e) {
}
void windowActivated(WindowEvent e) {
}
void windowDeactivated(WindowEvent e) {
}
}

----------------解决方案--------------------------------------------------------
public void windowOpened(WindowEvent e) {
}
public void windowClosing(WindowEvent e) {
System.exit(0);
}
public void windowClosed(WindowEvent e) {
}
public void windowIconified(WindowEvent e) {
}
public void windowDeiconified(WindowEvent e) {
}
public void windowActivated(WindowEvent e) {
}
public void windowDeactivated(WindowEvent e) {
}
全部改成这样就行了

谢谢，我刚解决了，谁这么无聊啊，在论坛放木马~~！

大伙还真热心啊，麻烦你们了，让你们看这么菜的问题。。

其实有的问题很简单 只要你细心的去找 肯定是能找到问题所在的
再说你不是在学Swing吗？怎么又会去搞AWT是呢 多打打书上的代码
----------------解决方案--------------------------------------------------------
不是这样的,学swing确实要用到awt 的东西
比如swing里面的大部份事件模型都是用awt里面的事件模型
----------------解决方案--------------------------------------------------------
f.addWindowListener(new MyWindowListener());
写成内部类,用WindowAdapter,代码便于阅读
f.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
----------------解决方案--------------------------------------------------------
不错,用适配器确实比直接用接口实现的内部类好看多了
你可以只重写你需要的方法
这样代码也精减了不少

我是看到他写的组件名才这么问的 事件是基本上2边用的都是一样的 有不一样的吗？
一般情况下 都是用的适配器和匿名类来写事件 通常情况下是不会写全部的监听器接口的 如果有需要的话 就不样了
