java: Using stream.forEach() or stream.forEachOrdered() on putting stuff into a set

Question

If I want to add elements from a stream to a set using stream().forEach(e->{set.add(e)}, would it have any problems? or am i supposed to use forEachOrdered() thank you.

Answer 1

It doesn’t make any difference until you use stream.paralle().foreach or foreachordered(). However since you are adding in set the items in the set may not be ordered. Refer to this link for details to understand difference between these two.
