This is a simple Java Class to create random 9x9 sudoku.
Enclosed to the Sudoku generator archives you will find as well a ready to run application based on this library.
Find more information about how to use this software on my website.
You will find there as well more information about the Java Applet example which has been created with this generator engine and details about the used backtracking method in this Java project.
This project has been renamed recently from JMLSudoku to OpenSudokuLib.
