That's all.

Unfortunately, those didn't work( because of type issues). So I made my own
integer one. :)
Anyways, somewhat unrelated question: I have attached a file that includes a
simple program that I've made for keeping the brain fit, with memory. I've also
made one that let's you do simple addition. :D
Anyways, everything is compiling fine, but I get an ArrayOutOfBounds error on
line 125 or something. 
Okay, it's function createArray, which is called by memoryTest. Line 114, 115.
The file is attached.
Does anyone know I'm getting these array errors?

line 125:	for ( int i = arrayToConvert.length; i > 0; i-- )

that should be:

for ( int i = arrayToConvert.length - 1; i > 0; i-- )

this is because arr[arr.length] is the elemant after the last element.

You mean i >= 0, I suppose.  ;)

No offense BCS, but for someone so well-spoken and intelligent, I'm kind of 
shocked at how poor/inconsistent your spelling is.  "elemant" and "element" 
in the same sentence?

Keep (gently) needling me on that. I need to do better.

OTOH I have on occasion wondered if I'm borderline dyslexic (My mind just 
doesn't seem to "see" spelling errors). I've never bothered to get tested 
so I can't claim it as a reason and even if I did get tested I can't claim 
it as an excuse*.

Really what I need to do is figure out how to get a spell checker plugged 
into my NG reader  :b

* there is a fun debate in that fine distinction

int[] memoryList;

Maaaaybe you can see it now.

Hint: how long is memoryList?

Oh. I just thought it dynamically allocated memory for each new element.
Anyways, I put memoryList.length = lengthOfList  above the for statement.
Anyways, thanks for the help. :)
