What are the differences between Java Streams and Spliterators?

Java Streams provide a high-level abstraction for processing sequences of elements, while Spliterators are lower-level constructs that allow for efficient traversal of data sources.

Can you give me an example of how to use both?

Sure! With Streams, you can use stream().filter() to process elements, while with Spliterators, you can create a custom iterator using Spliterators.spliterator().

Which one is more efficient?

It depends on the use case. Streams are more convenient for functional-style operations, while Spliterators can be more efficient for large data sets due to their lower overhead.

Are there any scenarios where I should prefer Spliterators over Streams?

Yes, if you need fine-grained control over the iteration process or are working with large data sets where performance is critical, Spliterators might be the better choice.
