具体内容如下：就是哪个什么windowslistener不对《不知为什么帮个忙，怎么才能让那个窗口正常关闭呢？

class MyClass implements WindowListener{
public void windowOpened(WindowEvent e){}
public void windowClosing(WindowEvent e){
System.exit(0);
}
public void windowClosed(WindowEvent e){}
public void windowActivated(WindowEvent e){}
public void windowIconified(WindowEvent e){}
public void windowDeiconified(WindowEvent e){}
public void windowDeactivated(WindowEvent e){}
}


这样就好了

在实现Frame的函数里加上addWindowListener(new MyClass());

dispose()
方法可以关闭

知道了，谢谢啊，但是为什么我向里面添加textfeild要手动拉动窗口，才会显示，我添加了panel了

可以用适配器的，你只要extends WindowAdapter就可以了，而不需要直接去实现WindowListener这个接口。这样你就不需要去重写那些没有实体的空函数了。

class MyClass extends WindowAdapter
{
public void windowClosing(WindowEvent e)
{
System.exit(0);
}
}

class MyWindowListener extends WindowAdapter{
        public void windowClosing(WindowEvent e){
        System.exit(0);}
       } ;
