Help with Java : creating a sudoku?
Hi.
I am currently working on a Sudoku using Java, and I'd like to write a function that returns a boolean and would check whether a grid is filled or not.
However, this is my first time with Java, and I am not sure how to proceed.
Help please!

That would depend on how you are storing the grid.
Personally, I would consider a grid filled if all 9 locations contain a value between 1 and 9 and would store it in a 2 dimensional array.
Since there are only 9 grids, 9 rows and 9 columns you could if you wanted to skip some of the logic and code in each grid manually instead of using a loop.
What have you done so far?
