监听3种实现

package chuangkou;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JFrame;

import lovo.Mytest;

public class TestFrame extends JFrame implements ActionListener {

     private MyTest nameText=new MyTest("姓名",70,50,this);

     public TestFrame(){

          this.setLayout(null);

          

          

          MyButton b=new MyButton("确定", 50, 50, this);

          /*

          b.addActionListener(new MyAction());*/

//        b.addActionListener(this);

          b.addActionListener(new ActionListener() {

              

              @Override

              public void actionPerformed(ActionEvent e) {

                   // TODO Auto-generated method stub

                   String info=nameText.getText();

                   System.out.println(info);

                   

                   

              }

          });

          this.setSize(500,400);

          //可见度

          this.setVisible(true);

          //关闭

          this.setDefaultCloseOperation(3);

          //居中

          this.setLocationRelativeTo(null);

     }

     public static void main(String[] args) {

          TestFrame t=new TestFrame();

     }

     @Override

     public void actionPerformed(ActionEvent e) {

          // TODO Auto-generated method stub

          System.out.println("*********************---");

          

     }

}

//第二种的class

package chuangkou;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

public class MyAction  implements ActionListener{

     @Override

     public void actionPerformed(ActionEvent e) {

          // TODO Auto-generated method stub

          System.out.println("********");

          

     }

}
