Question

如何在M-threads中运行我的任务N次？例如，我有一些任务

public static Runnable createTask () {
   Runnable runnable = new Runnable() {
     @Override
     public void run() {               
        System.out.println("simple task");
     }
   };
return runnable;
}

我需要N次运行此任务并将工作分成M个线程。

你走了。如果你想要运行相同的任务＆＃34; N＆＃34;时间，然后创造＆＃34; N＆＃34; Callable相同任务的实例，并将其添加到Callable List中，您将传递给invokeAll方法。

      try {
        List<Callable<Object>> callableList = new ArrayList<Callable<Object>>();
        callableList.add(null); /*Add instance of Callable*/
        callableList.add(null); /*Add instance of Callable*/
        callableList.add(null); /*Add instance of Callable*/

        //Specify how many threads you want or need to operate. Read other methods of Executors which return different instances of ExecutorService
        final ExecutorService service = Executors.newFixedThreadPool(3);

        //This will invoke all your N tasks in specified M threads ...
        service.invokeAll(callableList);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }

在不同的线程中运行任务
