[求助]我的这个如何编译？

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

class GUI extends JFrame
{
JButton btn1 = new JButton("Button 1");
JButton btn2 = new JButton("Button 2");
JRadioButton radYes=new JRadioButton("Yes",true);
JRadioButton radNo=new JRadioButton("No",false);
ButtonGroup radioGroup1 = new ButtonGroup();

RadioButtonListener rbListener=new RadioButtonListener();
ButtonListener btListener=new ButtonListener();

GUI()
{
Container c=getContentPane();
c.setLayout(null);

c.add(btn1);
c.add(btn2);
c.add(radYes);
c.add(radNo);

radioGroup1.add(radYes);
radioGroup1.add(radNo);

radYes.addActionListener(rbListener);
radNo.addActionListener(rbListener);
btn1.addActionListener(btnListener);
btn2.addActionListener(btnListener);

radYes.setBounds(30,30,50,40);
radNo.setBounds(30,80,50,40);
btn1.setBounds(130,30,200,40);
btn2.setBounds(130,80,200,40);

setSize(380,200);
setTitle("GUI Demo with Radio Button "+"and Button Listener");
setVisible(true);
setResizable(false);
}

}


不知道怎么搞的，我怎么编译都出现错误，楼主能不能帮帮我啊！小弟这里先谢谢了！

RadioButtonListener rbListener=new RadioButtonListener();
ButtonListener btListener=new ButtonListener();
这两句是哪里来的，你又没有定义RadioButtonListener,ButtonListener。
就算你定义了，你也是从别的Listener那里继承的吧
那么你至少要导入一个包import java.awt.event.*;

当然首先得谢谢楼主你的帮忙，不过遗憾的是我看的不是太懂，你帮我改的那程序太难了。有没有简单一点的啊，我也是刚开始学这个java，我那段程序是照抄的书上的一段，谁知道出现了错误 ，楼主你看能不能用简化点的语言来表达那个，让我好理解一下，这里先谢谢了！

----------------解决方案--------------------------------------------------------

可能是漏抄了2个继承了ActionListener的类吧

----------------解决方案--------------------------------------------------------
编译完后只有那两句有问题
那两个监听的接口
肯定没有声明！

----------------解决方案--------------------------------------------------------

我看了一下，成功了，太感谢楼主了，刚看了一下别人发的帖子，楼主真的很敬业！
