What are Java Streams and how can I use them in parallel?

Java Streams are a powerful abstraction for processing sequences of elements. You can use them in parallel by calling the parallelStream() method.

Can you give me an example of using parallel streams?

Sure! Here's a simple example: List<String> myList = Arrays.asList("a", "b", "c"); myList.parallelStream().forEach(System.out::println); This will print the elements in parallel.

What are the benefits of using parallel streams?

The main benefits include improved performance for large datasets and the ability to leverage multi-core processors.

Are there any downsides to using parallel streams?

Yes, parallel streams can introduce overhead and may not always lead to performance gains, especially for small datasets.
