Math.random() Arrrrrg!!!!!
Author
Im having another problem with my Math.random()method(java btw)
i have created a randomization function for a tic tac toe game and the whole thing seems ok except when it comes to runtime here is the source code:
please help me understand my mistakes it's the only way to learn and make progress
Thanks to all who respond,
Francis...
What, exactly, is the problem with it? I.e., what behavior do you expect, and what are you getting?

Nobody understands this?

Actually I think nobody would bother studying hundreds lines of code, especially since you're not even mentioning what the problem is.

I'm very sorry for not mentioning th problem, I was in a hurry it was the end of my lunch break and I wrote it fast and never rewrote it.
Well as you see in my calcPlacement method if there are no wins/ loses opportunities(or anything to play onto(in hard mode))(basically on the first turn. this is the expected output:
0 | 1 | 2
-----------
3 | 4 | 5
-----------
6 | 7 | 8
Enter Selection:
1
(computer responds here)
| X |
-----------
| | O
-----------
| |
but what happens:
0 | 1 | 2
-----------
3 | 4 | 5
-----------
6 | 7 | 8
Enter Selection:
1
(computer responds here)
O | X | O
-----------
O | O | O
-----------
| O | O
or something of the sort(randomly fills a whole bunch of squares)

A little more info on this problem:
I have made tests and this bug only happens when the randomPlacement() method is used in an if() statement,
This is the one bug stopping this game from being finished sop pleae help.
Thank you,
Francis...
