Hi,

I am trying to come up with a better way to store a score into a table that have X and Y axis.
It's just like 2D array, a score would be stored at the X's row and Y's column and I should be able to get that score using row and column number:

ie.
0 1 2 3 4
1 X X X X
2 X X X X
3 X X X X
4 X X X X

but here is my problem, 2D array work fine when I know the array size, but my input's size
depend on the input file that needs to be loaded into the application and their size are not fixed.

So right now, I end up using multiple ArrayList inside an ArrayList to simulate how the 2D array work, which solve the unfix input's size problem . But it just seem to be quite a messy way to solve this problem for me, so I was just wondering are there any other ways I could go about this?

Cheer!
