How do sequential and parallel streams differ in Java?

What are the main differences between sequential and parallel streams in Java?

Sequential streams process elements one at a time, while parallel streams divide the workload across multiple threads.

Can you give an example of when to use parallel streams?

Use parallel streams when processing large datasets that can benefit from concurrent execution, like in data analysis.

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.

How do I convert a sequential stream to a parallel stream?

You can convert a sequential stream to a parallel stream by calling the parallel() method on the stream.
