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！

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！

程序代码：

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;  //需要导入这个包

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();  //对RadioButtonListener类进行实例化
  ButtonListener btnListener=new ButtonListener();  //对ButtonListener类进行实例化
  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);
  }
  
  class RadioButtonListener implements ActionListener{  //内部类继承了ActionListener
   public void actionPerformed(ActionEvent e){
    
   }
  }
  
  class ButtonListener implements ActionListener{
   public void actionPerformed(ActionEvent e){
    
   }
  }
}

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！
