How can I use Java Streams with Sets?

You can use Java Streams to perform various operations on Sets, like filtering, mapping, and collecting results.

Can you show me an example of filtering a Set using Streams?

Sure! Here's an example: Set<String> names = new HashSet<>(Arrays.asList("Alice", "Bob", "Charlie")); You can filter it like this: Set<String> filteredNames = names.stream().filter(name -> name.startsWith("A")).collect(Collectors.toSet());

What if I want to convert a Set to a List using Streams?

You can easily convert a Set to a List by using the collect method. For example: List<String> nameList = names.stream().collect(Collectors.toList());

Are there any performance considerations when using Streams with Sets?

Yes, while Streams can be very convenient, they may introduce overhead. For large Sets, consider the performance trade-offs.
