JAVA多线程实现简单的点名系统

效果图如下：

CMain函数：

 package com.shubing.main;

 public class CMain
 {
     public static void main(String[] args)
     {
         MainFrame mainFrame = new MainFrame();
         mainFrame.setVisible(true);
     }
 }

MainFrame函数：

 package com.shubing.main;

 import java.awt.*;
 import java.awt.event.*;
 import javax.swing.*;

 public class MainFrame extends JFrame implements ActionListener
 {
     public static boolean flag = false;
     public JButton enter = new JButton("确定");
     public JButton exit = new JButton("退出");
     public JLabel text = new JLabel("点名");
     public JLabel name = new JLabel("姓名");
     public String[] nameList = {"王一","刘二","赵三","周四","马五","龙六","张七","贾八","钟九"};
     public JLabel message = new JLabel("学生总数："+nameList.length);
     public EnterThread mainThread = null;
     public MainFrame()
     {
         this.setTitle("点名系统");
         this.setSize(,);
         this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         this.setLocationRelativeTo(null);
         this.setLayout(null);    //布局为空;
         this.setFocusable(false);

         text.setBounds(, , , );
         name.setBounds(, , , );
         enter.setBounds(, , , );
         exit.setBounds(, , , );
         message.setBounds(, , , );

         this.add(text);
         this.add(name);
         this.add(enter);
         this.add(exit);
         this.add(message);

         enter.setEnabled(true);
         exit.setEnabled(false);

         Font font = new Font("华文行楷",Font.BOLD,);
         this.text.setFont(font);
         this.name.setFont(font);

         enter.addActionListener(this);
         exit.addActionListener(this);
     }

     @Override
     public void actionPerformed(ActionEvent e)
     {
         if(e.getSource() == enter)
         {
             mainThread = new EnterThread(this);
             mainThread.start();
             enter.setEnabled(false);
             exit.setEnabled(true);
         }
         if(e.getSource() == exit)
         {
             new ExitThread(this).start();
             exit.setEnabled(false);
         }

     }

 }

EnterThread函数：

 package com.shubing.main;

 public class EnterThread extends Thread
 {
     private MainFrame mainFrame = null;
     private boolean isStop = true;
     public int time = ;

     public EnterThread(MainFrame mainFrame)
     {
         this.mainFrame = mainFrame;
     }
     public void stopThread()
     {
         this.isStop = false;
     }
     public void run()
     {
         try
         {
             int index = ;
             while(isStop)
             {
                 if(index == this.mainFrame.nameList.length)
                 {
                     index = ;
                 }
                 this.mainFrame.name.setText(mainFrame.nameList[index]);
                 index ++;

                 Thread.sleep(time);
             }
         }
         catch (InterruptedException e)
         {
             e.printStackTrace();
         }
         this.mainFrame.enter.setEnabled(true);
     }
 }

ExitThread函数：

 package com.shubing.main;

 public class ExitThread extends Thread
 {
     private MainFrame mainFrame = null;

     public ExitThread(MainFrame mainFrame)
     {
         this.mainFrame = mainFrame;
     }

     public void run()
     {
         try
         {
             for(int i=;i<=;i+=)
             {
                 this.mainFrame.mainThread.time += i;
                 sleep();
             }
         }
         catch (InterruptedException e)
         {
             e.printStackTrace();
         }
         mainFrame.mainThread.stopThread();
     }
 }
