Sudokus can be loaded from a string, array or copied from another sudoku object by passing the argument to the constructor.
SudokuGenerator
SudokuGenerator generates different difficulty levels of puzzles:
int numberOfPuzzles = 10;
SudokuGenerator generator = new SudokuGenerator();
generator.generate(numberOfPuzzles, SudokuDifficulty.HARD);
List<Sudoku> results = generator.getSudokus();
SudokuSolvers
SudokuSolvers solve puzzles and create solutions:
SudokuPossibilityBasedSolver solver = new SudokuPossibilityBasedSolver(sudoku);
int numberOfSolutions = solver.solve();
Sudoku solution = solver.getFirstSolution();
PdfGenerator
PdfGenerator generates a PDF file with sudokus and their solutions.
SudokuFactory generator = new SudokuFactory();
List<Sudoku> sudokus = generator.generate(36, SudokuDifficulty.EASY);
try {
PdfGenerator.generateSudokuPdf("Furcino.com Sudokus","easySudokus.pdf", sudokus);
} catch (IOException e) {
fail("Could not generate PDF");
