Why doesn't this thread pool get garbage collected?

Question

In this code example, the ExecutorService is used one and allowed to go out of scope.

public static void main(String[] args)
{
    ExecutorService executorSe         


        

Answer 1

If you want the threads to be finalized when the Executor service is out of scope you should avoid, as mjt suggested, the use of

    ExecutorService executorService = Executors.newFixedThreadPool(3);`

and use for example:

ExecutorService executorService = new ThreadPoolExecutor(0, 3, 10, TimeUnit.MILLISECONDS, new LinkedBlockingQueue());
