The Sudoku Validator is a Java program that validates a Sudoku puzzle using multithreading. It checks if the given Sudoku puzzle is valid by ensuring that each row, column, and 3x3 subgrid contains the digits 1 through 9 without repetition.
To compile and run the Sudoku Validator program, you need to have the following installed on your system:
- Java Development Kit (JDK) 8 or above
-
Clone the repository or download the source code files.
-
Open a terminal or command prompt and navigate to the directory where the source code files are located.
To run the Sudoku Validator program, use the following command:
java SudokuValidator
This command executes the main()
method in the SudokuValidator
class, which demonstrates the usage of the Sudoku Validator.
The program uses a predefined Sudoku puzzle grid for validation. If you want to validate a different Sudoku puzzle, you can modify the grid
array in the main()
method of the SudokuValidator
class.
Update the values in the grid
array to represent your Sudoku puzzle. Each row of the puzzle corresponds to a subarray in the grid
array, and each digit in the puzzle is represented by an integer value.
For example, to validate a different Sudoku puzzle, you can modify the grid
array as follows:
int[][] grid = {
{6, 3, 4, 6, 7, 8, 9, 1, 2},
{6, 7, 2, 1, 9, 5, 3, 4, 8},
{8, 9, 8, 3, 4, 2, 5, 6, 7},
{8, 5, 9, 7, 6, 1, 4, 2, 3},
{4, 2, 6, 8, 5, 3, 7, 9, 1},
{7, 1, 3, 9, 2, 4, 8, 5, 6},
{9, 6, 1, 5, 3, 7, 2, 8, 4},
{2, 8, 7, 4, 1, 9, 6, 3, 5},
{3, 4, 5, 2, 8, 6, 1, 7, 9}
};
This command compiles the SudokuValidator.java
file and generates the corresponding .class
files.
After modifying the grid
array, save the changes and recompile the program using the javac
command mentioned earlier.
After running the program, it will display the validation result in the console. If the Sudoku puzzle is valid, it will print "The Sudoku puzzle is valid."
Otherwise, it will print "The Sudoku puzzle is not valid."
If you encounter any issues while compiling or running the program, ensure that you have Java Development Kit (JDK) installed correctly and the necessary environment variables are set up properly.
