If you had just this :
Optional<String> ops = names.stream().parallel().findAny();
It could potentially print any name from the list because of .parallel().

Technically, it could print an Optional containing any name from the list.

Well, from that perspective it should say, it could potentially print an Optional containing a String containing chars for any name from the list
Since it is making a general statement about the code snippet whose last line is System.out.println(ops);, I think it is ok to say that it prints name. The fact that it prints an Optional is quite clear because we are indeed passing an Optional to println.

Hi Admin

If you had just this :

Code: Select all

Optional<String> ops = names.stream().parallel().findAny();

It could potentially print any name from the list because of .parallel().

My understanding is that it could potentially print any name from the list because of findAny. I.e. whether parallel is used or not, the behaviour is the same.

Thanks.

Just want to confirm one thing: we can't chain any terminal operation after another terminal operation, right? so, there is only one terminal operation is allowed in the stream.

Yes and you should also understand the reason why.

Cause terminal operations does not return stream?

Correct.
