Question

Write a Java program using GUI to create a game of Sudoku. You will have to fill a 9×9 grid with digits 1 to 9 , so that each column, each row, and each of the nine 3×3 boxes contain all the digits from 1 to 9 . You can built the interface with using simple textboxes.

Answer 1

To create a Java program with a GUI to play Sudoku, you can use textboxes to represent the grid and implement input validation and solving algorithms.

Step-by-step explanation:

To create a game of Sudoku using Java and GUI, you can use textboxes to represent the 9x9 grid. Here are the steps:

1. Create a GUI interface with 81 textboxes arranged in a 9x9 grid.
2. Implement logic to input and validate user input in each textbox.
3. Write a validation algorithm to check if the Sudoku puzzle is solved correctly.
4. Implement a backtracking algorithm to solve the Sudoku puzzle automatically.
5. Display the solved puzzle on the GUI interface.

By following these steps, you can create a Java program with a GUI interface to play Sudoku.
