Java ForkJoinPool

The Java ForkJoinPool helps you break down large tasks into smaller subtasks which can be executed in parallel using all, or some, of the CPU cores available in your computer. The Java ForkJoinPool thus helps you implement a fork and join type of work break down and parallelism.

The Java ForkJoinPool implements a work stealing algorithm which further helps utilize the CPU cores in your computer more efficiently. This work stealing algorithm is also explained in this Java ForkJoinPool tutorial.
