Have you used data stream APIs in your projects?

Yes, the Streams API in Java is widely used for processing collections and sequences of data in a functional style.

With streams, you can perform filtering, transformation, sorting, and aggregation operations more concisely and efficiently.

Example of using the Streams API:

List<String> names = Arrays.asList("Anna", "Bob", "Charlie", "David");

List<String> filtered = names.stream()
    .filter(name -> name.startsWith("A"))
    .map(String::toUpperCase)
    .collect(Collectors.toList());

System.out.println(filtered); // [ANNA]

In projects, I have used streams to process data from databases, files, and APIs, which allowed me to write cleaner and more readable code.
