What are the differences between parallel streams and ForkJoinPool in Java?

Parallel streams are a high-level abstraction for parallel processing in Java, while ForkJoinPool is a lower-level framework for managing threads.

Can you explain how parallel streams work?

Sure! Parallel streams utilize the ForkJoinPool to split tasks into smaller chunks, processing them concurrently to improve performance.

When should I use ForkJoinPool instead of parallel streams?

Use ForkJoinPool when you need more control over task execution, such as managing thread behavior or handling complex task dependencies.

Are there any performance considerations I should be aware of?

Yes, parallel streams can introduce overhead for small tasks, so it's best to use them for larger datasets. ForkJoinPool allows for more fine-tuned performance adjustments.

Can you give an example of using ForkJoinPool?

Certainly! You can create a ForkJoinPool instance and submit tasks using RecursiveTask or RecursiveAction to perform parallel computations.
