let's look at your reply for a second. You provided no help, only
criticism.
IMO, that's not accurate. If someone wants to succeed as a programmer,
they need to find solutions of all kinds. And when they get stuck and
need to reach out, they should "show their work" and put some thought
into their question.
Something about teaching them to fish rather than giving them a fish
comes to mind.
I find it hard to believe that they didn't know this wasn't a NetBeans
list. If they truly didn't, then the most help might be to give them
some hints on how to best fish the internet sea.
Well, I'm also member of the NetBeans Telegram group, and I have a
feeling, that the strongest foothold of NetBeans is in the academics as
a primary tool to teach Java. After all, it's free, works
out-of-the-box, and the provided Ant projects templates allows students
to create their first simple programs without the need to learn anything
about how to deal with the Java Runtime and packaging. I have the
feeling that many of these students are not necessary would like to be a
real developer. They just want to have their exam done / get some
credits. NetBeans is often synonym to Java, so they often end up posting
some "interesting" things here and NetBeans Telegram group as well.
Is it annoying to see such questions from time to time? As a
professional, I'd say yes, though it is not an obligation to anyone to
answer or interfere. This guy had his answers, so let him be happy with
those. I think it is Ok to be harsh/raw in your answers as long as they
are constructive.

The person asking the question wanted help. Rather than your acerbic
answer, you might have provided some aid and direction. You did say
that this list is for Netbeans issues only. That is help. You did say
that there are other places to look, with an implied criticism that
no looking was done. Moreover, you neglected to mention any single
place where help could have been found.
In my experience on this list, I have found many people who tried to
be helpful. The person asking the question was not asking for a
fight, and probably did not know the fundamental purpose of this
list. The question asker would have certainly gone elsewhere if it
was known that this list was for Netbeans, not Java.
Your comments are unwarranted and not helpful. If you felt annoyed
you should not have commented, or been more gracious in your comments.

So...
Other people on this list have attempted to help prior to this
reply. They are much nicer than I.
1. You *never* asked a question. You posted a bit of code and
indicated there was an error. You didn't indicate that you tried
to figure out the error or anything else. The people who
subscribe to this list aren't your parents and are under no
obligation to try to read your mind (assuming your parents have
that obligation) to solve your _unstated_ problems.
2. This mailing list is to discuss Netbeans issues. Basic java
problems really shouldn't be addressed here, although I might be
in the minority in this mailing list with that opinion.
There are ample places other than this list to find an answer to
your implied problem.
