What are sequential streams in Java's Stream API?

Sequential streams in Java's Stream API allow you to process collections of data in a single-threaded manner, meaning operations are performed one after the other.

Can you give me an example of how to use a sequential stream?

Sure! Here's a simple example: you can create a list of integers and use a sequential stream to filter even numbers like this:

List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5);
List<Integer> evenNumbers = numbers.stream()
                                     .filter(n -> n % 2 == 0)
                                     .collect(Collectors.toList());

What are the advantages of using sequential streams?

The main advantages include simplicity in code, easier debugging, and better performance for smaller datasets since there's no overhead of managing multiple threads.

Are there any limitations to using sequential streams?

Yes, sequential streams may not utilize multiple cores effectively, which can lead to slower performance on large datasets compared to parallel streams.
