What are Java Streams and how do I use them?

Java Streams are a powerful abstraction for processing sequences of elements, allowing for functional-style operations on collections.

Can you give me an example of using Java Streams to filter a list?

Sure! You can use the filter method to filter elements. For example: list.stream().filter(x -> x > 10).collect(Collectors.toList());

What are the benefits of using Streams over traditional loops?

Streams provide a more readable and concise way to process data, support parallel processing, and can be chained for complex operations.

Are there any performance considerations I should be aware of?

Yes, while Streams can improve readability, they may introduce overhead. It's important to benchmark performance for critical paths.
