如何在M线程中N次运行任务？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;
}
我需要运行此任务N次，并将工作划分为M个线程。
干得好。如果您希望同一任务运行“ N”次，则创建Callable同一任务的“ N”个实例，并将其添加到Callable List您将传递给invokeAll方法的实例中。
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();
}
