如何仅执行一个线程并接收Future而无需创建ExecutorService？

Question

I need to execute only aa single thread with the ability to cancel it. I found that I can achieve this using Future<T> s. Right now I use it like this:

ExecutorService executorService = Executors.newSingleThreadExecutor();
Future<Void> future = executorService.submit(copyCallable);
executorService.shutdown();

Since ExecutorService s are usually used to manage a multiple threads, I was wondering if there was a more efficient way to achieve this without creating one. Thanks.

Interryprion is implemented by both Thread and calling method. Your thread need to listen for InterruptedException or check interruption flag at convenient points in time. Calling code should call t.interrupt() for notifying Thread that it should stop.
