java - 如何在特定时间后继续运行线程

Question

我有一个线程，我想每 15 分钟运行一次。目前我正在从另一个类调用这个线程，比如

Class B{
public void start(){
 while(true){
 new Thread(new A()).start();
   }
 }
}

Class A implements Runnable{
  @override
  public void run(){
   //some operation
  }
}

如何每 15 分钟调用一次线程 A。

Answer 1

您可以使用 Timer或 ScheduledExecutorService以一定间隔重复一项任务。

An ExecutorService that can schedule commands to run after a given delay, or to execute periodically.

示例代码:

ScheduledExecutorService executorService = Executors.newScheduledThreadPool(1);

executorService.scheduleAtFixedRate(new Runnable() {
    public void run() {
        System.out.println("Asynchronous task");
    }
}, 0, 15, TimeUnit.MINUTES);
