Is hashCode() supposed to be used for this purpose? I thought that was always supposed to have a generated value unique for every object instance.
Are you trolling? You've been participating in this forum for
upwards of three years, and last year you said you'd been writing
Java "for probably about 10 years" -- and we're supposed to believe you
don't know what equals() and hashCode() are for?
Benefit of the doubt: I guess it's just barely possible that after
eleven-ish (claimed) or three-plus (shown) years of Java involvement
you might actually be unfamiliar with the basics. You have shown more
than once that your grasp of Java concepts is less than firm, and I have
speculated that you may be trying to write Java by "faking it" with an
extensive knowledge of other languages. (I still consider that the most
likely explanation for your blunders, although the Troll Hypothesis is
beginning to gain credibility.) But just in case you're not trolling,
