嘗試是這樣的方法：

import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 

import javax.swing.ButtonGroup; 
import javax.swing.JPanel; 
import javax.swing.JToggleButton; 

class buttonGroup implements ActionListener 
{ 
    JToggleButton yes[], no[]; 
    JPanel yesNo[]; 
    ButtonGroup group[]; 

    public void init() 
    { 
     yesNo = new JPanel[60]; 
     yes = new JToggleButton[60]; 
     no = new JToggleButton[60]; 
     group = new ButtonGroup[60]; 
     for(int i = 0; i < 60; i++) 
     { 
      yesNo[i] = new JPanel(); 
      yes[i] = new JToggleButton("yes"); 
      yes[i].setName("yes" + " " + i); 
      yes[i].addActionListener(this); 
      no[i] = new JToggleButton("no"); 
      no[i].setName("no" + " " + i); 
      no[i].addActionListener(this); 
      group[i] = new ButtonGroup(); 
      yesNo[i].add(yes[i]); 
      yesNo[i].add(no[i]); 
      group[i].add(yes[i]); 
      group[i].add(no[i]); 
     } 
    } 

    public void actionPerformed(ActionEvent sE) 
    { 
     if(sE.getSource() instanceof JToggleButton) 
     { 
      JToggleButton oSourceButton = (JToggleButton) sE.getSource(); 
      System.out.println("Button " + oSourceButton.getName() + " was pressed..."); 
      // do whatever... 
     } 
    } 
}
