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);

     }

 }
