Detailed difference between Java8 ForkJoinPool and Executors.newWorkStealingPool?

Question

What is the low-level difference among using:

ForkJoinPool = new ForkJoinPool(X);

and

ExecutorService ex = Executors.neWorkStea         


        

Answer 1

It's only a abstraction for the Fork/Join Framework...

/**
* Creates a work-stealing thread pool using all
* {@link Runtime#availableProcessors available processors}
* as its target parallelism level.
* @return the newly created thread pool
* @see #newWorkStealingPool(int)
* @since 1.8
*/
public static ExecutorService newWorkStealingPool() {
    return new ForkJoinPool(Runtime.getRuntime().availableProcessors(),
                            ForkJoinPool.defaultForkJoinWorkerThreadFactory,
                            null, true);
}
