java匿名类 找不到符号

import java.awt.event.*;
public class ee

int m=n*n;

text1.addAcitonListener(new ActionListener()//ee.java:20:找不到符号
改为：
text1.addAcitonListener(new ActionListener implements ActionListener()

注册监视器和方法实现都没有问题，你试着把swing包导入。
import javax.swing.*;

import java.awt.*;
import java.awt.event.*;
//下面加他不就可以了吗？？？
import java.awt.event.ActionListener

是找不到包吧！

ActionListener是个接口吧？类要实现接口所有的方法 除非是抽象类

package baidu.answer;

import java.awt.*;
import java.awt.event.*;

public class ee {
public static void main(String args[]) {
HisWindow win = new HisWindow();
}
}

class HisWindow extends Frame {
TextField text1, text2, text3;

HisWindow() {
text1 = new TextField(15);
text2 = new TextField(15);
text3 = new TextField(15);
setLayout(new FlowLayout());
add(text1);
add(text2);
add(text3);
Policeman police = new Policeman();
text1.addActionListener(police);
