The file format that the program saves is identical to the format used for loading, so cell values can be saved and re-loaded.
Validating Validate the Board:
Clicking the {Validate}} button will pop up a message dialog box with information on the state of the board. This button, which is fully operational in the supplied code, is a very useful tool to check your code's performance as you work. The information shown includes
- If the board is solved.
- If the board is valid but not solved. The board could be irreducible however.
- The board is invalid
- The same value appears more than once -- the offending row, column or block is shown
- An invalid value is present, e.g. a negative number -- the offending row, column or block is shown.
- A cell is empty - Only one empty cell per cell set is detected. There may be more empty cells present.
All recution and solving operations should always leave the board in a valid state, unless the board is unsolvable, wherein a cell may become empty.
See the note about the GameModel.validateBoard() method in the Code Details wiki page!!
