在java中是否有Thread.sleep的替代品

问题描述

这是我的代码

while (true) {
    try {
        Thread.sleep(5 * 60 * 1000);
        processData();// data processing job
    } catch (InterruptedException e) {
        SystemMessageBillPay.getInstance().writeMessage("ERROR: CEB.run() - " + e.getMessage());
    } catch (NumberFormatException e) {
        SystemMessageBillPay.getInstance().writeMessage("ERROR: CEB.run() - " + e.getMessage());
    }
}

到此

代码检查员发出警告

防止此警告的代码应该是什么

推荐答案

Is there a alternative to Thread.sleep

是的，有办法。 但是，

看起来你想安排一些工作。您可以使用或而不是此。所以后面的部分问题是关于

It looks like you want to schedule some job. You can either use TimerTask or ScheduledExecutorService instead of this. So later part of your question is about the

这将通过安排任务来解决。

and this will solve with scheduling the task.

安排任务。

public class Test extends TimerTask{

public static void main(String[] args) {
  Test task = new Test();
  Timer timer = new Timer();
  Calendar today = Calendar.getInstance();
  today.set(Calendar.HOUR_OF_DAY, 13);
  today.set(Calendar.MINUTE, 47);
  today.set(Calendar.SECOND, 0);
  timer.schedule(task, today.getTime(), TimeUnit.MILLISECONDS.convert(1, TimeUnit.DAYS));
}

 @Override
public void run() {
 System.out.println("Running Scheduled Task...!!!");
}
}
