1、 用Thread就不会iu无法终止

new Thread(new Runnable() {            public void run() {                while (true) {                    test();                    try {                        Thread.sleep(500);                    } catch (InterruptedException e) {                        // TODO Auto-generated catch block                        e.printStackTrace();                    }                }            }            private void test() {                // TODO Auto-generated method stub            }            public Runnable start() {                // TODO Auto-generated method stub                return null;            }        }.start());

2、 或者用现成的

javax.swing.Timer timer = new javax.swing.Timer(500, new ActionListener() {   public void actionPerformed(ActionEvent e) {     repaint();   } };

timer.start();

3、下面这个方法测试过可以用 java非线程延时

import java.awt.Robot;import java.util.Date;public class test {     public   static   void   main(String[]   args)   throws   Exception{            Robot  r   =   new   Robot();          System.out.println( "延时前:"+new Date().toString()  );          r.delay(   2000   );            System.out.println(   "延时后:"+new Date().toString()   );      }   }

 

  4、 用这下面的TimeTask类(指定延时)

java里面的sleep()并不能精确定时,TimeTask可以:例下面的小程序:

import java.util.*;public class test {    public static void main(String[] args) {        Timer timer = new Timer();// 实例化Timer类        timer.schedule(new TimerTask() {            public void run() {                System.out.println("退出");                this.cancel();            }        }, 5000);// 这里百毫秒        System.out.println("本程序存在5秒后自动退出");    }}
