How can I improve the performance of parallel streams in Java?

How can I improve the performance of parallel streams in Java?

To improve performance, ensure that your data is large enough to benefit from parallelism and avoid using shared mutable state.

What are some common pitfalls when using parallel streams?

Common pitfalls include using parallel streams on small datasets, which can lead to overhead, and modifying shared data.

Can you give an example of a good use case for parallel streams?

A good use case is processing large collections of data, like filtering or mapping, where tasks can be done independently.

How do I measure the performance of my parallel streams?

You can use the System.nanoTime() method to measure execution time before and after your parallel stream operations.
