How to create ForkJoinPool with 10 threads?
Class contains 3 constructors, but only in first is declared that by default will be used number of processors. For other is used int parallelism, but it does not sound like threads cound.

You can't explicitly specify the number of threads. As you have noted, you can specify the level of paralallism, which is basically implemented using threads.
