Please help! I know I don't post here much, in fact, I don't post here at all, but this does not mean I am just some noob trying to get some easy code. I have been in programming for two years, and signed up to this website about the same time. I signed up because I was interested in programming, and thought I could make some useful contributions. Well, I was wrong! You guys knew way more than I do, and still do, as I am still a beginner Java programmer. So, I decided I would just lurk and watch conversations to try and gather up as much info as possible, and it helped, getting me through some tough programs. I was confident to say that I never had to ask for help on anything, because most of the time I could figure it out myself using the knowledge I gained with experience and by visiting this site. Well, that has changed!
I have been assigned a sudoku program that must check the answers of a Sudoku puzzle. Basically, the teacher inputs 9 rows and 9 columns of numbers, and the output must show if the row is ok(meaning none of the same numbers in the row), the column is ok, and the subgrid(3x3 square). I have no clue how I am going to get this done, all I know is I need a 2D Array! Sorry for the essay but can you guide me in the right direction?
