Question

I\'m attempting to retrieve n unique random elements for further processing from a Collection using the Streams API in Java 8, however, without much or any luck.

Answer 1

It should be clear that streaming the collection is not what you want.

Use the generate() and limit methods:

Stream.generate(() -> list.get(new Random().nextInt(list.size())).limit(3).forEach(...);
