Parallel Stream
Explore the concept of parallel streams in Java 8 to efficiently utilize multicore CPUs for faster data processing. Understand how to create parallel streams, their internal thread management using ForkJoinPool, and important considerations for when to use parallel processing to ensure optimal performance and thread safety.

Until now, we have only been looking at serial Stream. However, Java 8 introduced the concepts of the parallel stream and parallel processing. As we have a greater number of CPU cores nowadays, due to cheap hardware costs, parallel processing can be used to perform operation faster.
Creating a parallel stream
There are two ways in which we can create a parallel Stream:
- Using the
parallelStream()method. - Or, if we already have a stream, we can use the
parallel()method to
