Or a LinkedHashFoo of some stripe.

Gene seems to be saying elsethread that in his real code he might
be initializing from something that isn't in order.  But assuming he
could put it in order before initializing the set, then yes, it seems
like a LinkedHashSet would do what he wants.

I added it to my benchmark suite, reran timing experiments, and found
LinkedHashSet to give performance very similar to that of HashSet.

A day in which I learned something new -- not bad.  Thanks!

If you care enough about performance to have put some effort
into benchmarking various approaches, I'd have thought you'd be
interested in one that seems to be significantly faster and almost
as simple to set up and use.  (Probably -- I guess it depends on
how, in your real code, you'll be initializing the set.)

I'm not unsympathetic, though, to a desire to move on once 
an acceptable solution has been found.  "Just sayin'", maybe.

     But why should I write code to sort something when SortedSet will
do it for me?  Plus, if I output the contents of the set, having it in
sorted order makes more sense.

     Remember that I am learning my way around Java.  You may already
know how to do it quickly.  For me, it would be another thing to find
and figure out.  In time, in time.

     Micro-optimisation is a nasty sin.

Yeah, yeah ....  I guess it just seems strange to me that you went to
all the trouble of writing code to benchmark various approaches --
suggesting that sometimes you *do* engage in micro-optimization --
but are resistant to trying one more approach that (in my tests
anyway) sometimes reduced execution time by almost 50%.  Just sayin',
"whatever", ....  :-)?

     It should be obvious to you why someone might do that.

     The part that I was benchmarking is critical to my program.  It
is repeatedly used since it is called for every non-newline character
in a file.  Initialising a set of characters does not happen nearly so
often.

I know I don't always express myself with 100% clarity, but really,
I must be doing worse than usual here ....

I did not attempt to measure speed of initialization.  That would
indeed be silly, and I don't understand why you would think ....
Well, be that as it may:

What I did was add to your benchmark code a test for LinkedHashSet,
identical to the one for TreeSet except for the type of set.  When 
I ran the resulting code, the output indicated that LinkedHashSet
was sufficiently faster than TreeSet for me to think you might
be interested.  "Faster" here means "faster by your criterion as
I understand it".  If you've made a decision and want to stop
dithering about whether you might have missed something someone
thinks might suit you better, okay, but ....  Well, whatever.

By the way, I'm still mildly curious about why you decided, without
testing, that it would not be a good idea to follow the suggestions
you were given about avoiding all that tedious cut-and-paste.  In

It's interesting to me that you were able to reach this conclusion
(that using Java's alternative to function pointers *does* affect
benchmarking results) without doing any experiments -- I think
you're probably right, but I did some experiments before coming to
the same conclusion.  "Whatever" again.

     Because it was a test program.  I was not going to keep the code.
I have not thrown it out yet, but I could.  Its job is done.  The
"real" program only has one type of search, namely the one that I
found to be fastest (using TestSet).

     I had no easy way to test, was fairly confident of the result of
any such test, and it almost certainly did not matter.  For the
search, none of those conditions were so.

     At some point, one has to do something in order to end up having
done something.

Now you're being rude. Why don't you a) get your own from line and quit 
using someone else's and b) talk about Java, or else c) get the fuck off

What the hell are you babbling on about now? Have you been drinking or 
something? You're not making an ounce of sense and you're obviously not 
oriented to place or person, since this is a Java newsgroup and there 
are no Pauls or Paolos here but you're babbling on about some people 
with those names and not saying anything about Java.
