新手求教大神，java事件监听问题

Question

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

import javax.swing.JButton;
import javax.swing.JLabel;

public class EventModelDemo implements ActionListener{
JLabel tips=new JLabel("请单击下面的按钮");
JButton b1=new JButton("确定");
JButton b2=new JButton("取消");

    public static void main(String[]args){
        EventModelDemo demo=new EventModelDemo();
        demo.initUI();
    }
  void initUI(){
        BaseFrame f=new BaseFrame("事件处理模型演示");
        f.setLayout(new FlowLayout());
        b1.addActionListener(this);
        b2.addActionListener(this);
        f.add(tips);
        f.add(b1);
        f.add(b2);
        f.showMe();

    }
    public void actionPerform(ActionEvent e){
        if(e.getSource()==b1){
            tips.setText("你单击了”"+b1.getText()+"”");

        }else if(e.getSource()==b2){
            tips.setText("你单击了“"+b2.getText()+"”");
        }
    }

    }
    在EventModelDemo出提示：The type EventModelDemo must implement the inherited abstract method ActionListener.actionPerformed(ActionEvent)

Answer 1

你继承自ActionListener接口，所以你要实现ActionListener接口中的方法，你肯定有的方法还未实现
