Help - Running Sudoku Game
I am trying to get this code to work, I am not really sure of the problem with it. I am using JCreator to write/compile/run it. When I compile it, it compiles fine but gives this message. "Note: C:\JFiles\Exercises\Sudoku.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details." I'm kinda new to this, so any help would be appreciated.
