Java 定时器（Timer,TimerTask）详解及实例代码

public class TimeTest { public static void main(String[] args) { Timer timer = new Timer(); timer.schedule(new MyTask(),1000,2000); }

public class MyTask extends TimerTask{ @Override public void run() { System.out.println("开始运行"); } }

public class SerchRun { protected static void startRun(){ Timer timer = new Timer(); TimerTask task =new TimerTask(){ public void run(){ System.out.println("开始运行"); //在这写你要调用的方法 } }; timer.scheduleAtFixedRate(task, new Date(),2000);//当前时间开始起动 每次间隔2秒再启动 // timer.scheduleAtFixedRate(task, 1000,2000); // 1秒后启动 每次间隔2秒再启动 } public static void main(String[] args) { SerchRun.startRun(); } }

SimpleDateFormat fTime = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss"); Date d1 = fTime.parse("2005/12/30 14:10:00"); t.scheduleAtFixedRate(new TimerTask(){ public void run() { System.out.println("this is task you do6"); } },d1,3*60*1000);

this is task you do6 //14:10 this is task you do6 //14:13 this is task you do6 //14:16
