Answer 1

public class yourClass extends JFrame implements ActionListener 

之后：

button1.addActionListener(this); 
// repeat for every button 

然后实现actionPerformed方法

public void actionPerformed(ActionEvent e){ 

    Object obj = e.getSource(); 
    if (obj == button1){ 
     // Your Code 
    }//else if .... 
}
