Create a command line tool (running on jvm) for validating a standard 9x9 Sudoku puzzle:

Command line: validate.bat puzzleName.txt

File format: csv format each line representing a row e.g.:

1,2,3,4,5,6,7,8,9
1,2,3,4,5,6,7,8,9
1,2,3,4,5,6,7,8,9
1,2,3,4,5,6,7,8,9
1,2,3,4,5,6,7,8,9
1,2,3,4,5,6,7,8,9
1,2,3,4,5,6,7,8,9
1,2,3,4,5,6,7,8,9
1,2,3,4,5,6,7,8,9

The program should return 0 (VALID) or non-zero (INVALID) value with an error text on stdout (in case of an invalid solution or file).
