How could i write two methods... one recursive and one not to fill a two dementional array of size n.

ex. 5 x 5 array

0 1 2 3 4
15 16 17 18 5
14 23 24 19 6
12 22 21 20 7
12 11 10 9 8

the non-recursive routine would be like void spiralFill(int [][]a, int n) where it spiral fills the first n rows and columns

Welcome to the Ranch.

Please post what you have got so far; we don't simply hand out answers to that sort of question. Read this.
I am not sure what the difference between spiral filling and ordinary filling is.

I think I have worked out what you mean by spiral filling. I tried it and failed. It's bl**d* difficult.
I agree. Here's the link:
