是否可以在特定时间在Java中调用方法?例如,我有一段这样的代码:
class Test{ public static void main(String args[]) { // here i want to call foo at : 2012-07-06 13:05:45 for instance foo(); } }
如何在Java中完成此操作?
使用java.util.Timer类,您可以创建计时器并将其计划为在特定时间运行。
下面是示例:
//The task which you want to execute private static class MyTimeTask extends TimerTask { public void run() { //write your code here } } public static void main(String[] args) { //the Date and time at which you want to execute DateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); Date date = dateFormatter .parse("2012-07-06 13:05:45"); //Now create the time and schedule it Timer timer = new Timer(); //Use this if you want to execute it once timer.schedule(new MyTimeTask(), date); //Use this if you want to execute it repeatedly //int period = 10000;//10secs //timer.schedule(new MyTimeTask(), date, period ); }
