Sudoku 16 X 16

It is a game of sudoku, the methods are all correct (I have omitted)
The problem is that I can not get my battery to work.
I want to create a stack of int [paintings]] [, and when the user enters "return"
I want the stack of pop, then I print.
I go back, but each, it returns an error NumberFormatException.
can someone tell me what's wrong? I'ved asterisks added for parties problem, much is not necessary to understand the problem, I think. Excuse the poor formatting ... it is wasted here.
