When to Use a Parallel Stream in Java ?

Using a parallel stream in Java can significantly enhance the performance of a program by leveraging multiple cores of the CPU to perform parallel processing.

Here are some scenarios when using a parallel stream is beneficial:

1. Large Data Sets :
   Parallel streams are particularly effective when dealing with large collections of data. They can split the data into smaller chunks and process them in parallel, reducing the overall processing time.
2. Performance Improvement: If the task involves significant computation…
