初学java之触发响应事件举例子

设置一个触发响应事件?

比如消息框.....

 package hello;
 import javax.swing.*;
 import project.readerListen;
 import java.awt.*;
 import java.awt.event.*;
 class WindGrid extends  JFrame{

     JTextField text;
     ActionListener listener;    

     public WindGrid(String title)
     {
       setTitle(title);
       init();
       setBounds(,,,);
       setVisible(true);
       setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     }    

     void init()
     {
       text = new JTextField();
       listener = new ReaderListen();  //自定义的 那个类
       setLayout(new FlowLayout());
       text.addActionListener(listener);
       add(new Label("输入蚊子 "));
       add(text);
     }

 }
 public class test {
     public static void main(String args[])
     {
       new WindGrid("第一个窗口");
     }
 }

 package hello;

 import java.awt.event.ActionEvent;
 import java.awt.event.ActionListener;
 import javax.swing.*;
 public class ReaderListen extends JFrame implements ActionListener
 {

     public void actionPerformed(ActionEvent e)
     {
     // TODO Auto-generated method stub
         JFrame myjframe;
         myjframe = new JFrame();
         JTextArea mytest;
         mytest =new JTextArea(e.getActionCommand(),,);
         myjframe.add(mytest);
         myjframe.setBounds(, , , );
         myjframe.setVisible(true);

     }
 }
