Executors.newWorkStealingPool() method returns a new work-stealing thread pool that uses all available processors as its target parallelism level. This method creates a new ForkJoinPool instance and sets its parallelism to the number of available processors.
Work-stealing thread pool is a special kind of thread pool that uses a work-stealing algorithm to distribute tasks among worker threads. In a work-stealing thread pool, worker threads are organized into a deque (double-ended queue), and tasks are added to the head of the deque. Each worker thread continuously tries to steal tasks from the tail of other worker threads' deque if its own deque is empty. This algorithm helps to balance the workload among worker threads and maximize CPU utilization.
The returned ForkJoinPool instance can be used to submit tasks using the execute() or submit() methods. The pool will automatically create and manage worker threads as needed.
Example usage:
```
ExecutorService executor = Executors.newWorkStealingPool();
executor.execute(() -> System.out.println("Task 1"));
executor.execute(() -> System.out.println("Task 2"));
executor.execute(() -> System.out.println("Task 3"));
```
