Maven is where it's at. The project needs some build configuration anyway so it can be built as an executable, dependency-free JAR file.

When using the manual input of typing into a Sudoku board, there is not undo button, which is okay as adding this would be an addition to the software. However, when you type in a digit which cannot be in that specific box, the software will come up with an error message, and the Board will appear unchanged. The board has actually accepted this incorrect number, and will not let the user type into this box, making the whole board fail, and all previous input must be put in again. It would be a great help to have the software which does not accept incorrect input to not put it in the board (not the interface). Even better would be the addition of an undo button which could allow the user to undo their mistakes.

If you do two things and then undo them, then you can only redo the first thing.
