Hello,

Thanks for your time. I need help with writing a tic tac toe game, a certain way. It has the be this way, it cannot be written any other way.

Example 1 -

So, for example this set of input would allow X to win along the main diagonal.

0 0

1 0

1 1

2 0

2 2

Alternatively, the input could be provided in one line:

0 0 1 0 1 1 2 0 2 2

The first pair is for Xs move, second pair for Os move and so on. If you are not having enough input values you will have an error.

Example 2 -

Another possibility is O to win in last column. The input values could be:

1 00 22 00 1 2 1 0 0

This is my the code I have so far. I don't understand how to get it to work if the user inputs his/her data like 01 22 02 12 etc. I am looking for your guidance and help, thank you.

import java.util.Scanner; public class Main { public enum Value { X, O; } private static Value[][] gameBoard = new Value[3][3]; public Main() { } public static void main(String[] x) { Main game = new Main(); Scanner s = new Scanner(System.in); int moves = 0; int row = -1, column = -1; boolean player = false; System.out.print("To enter moves like 0 0 1 0 2 2, enter 3 now: "); String input = ""; while (true) { Value mark = player ? Value.O : Value.X; if (s.nextInt() == 3) { System.out.print("Enter your moves number then space" + " starting with player " + mark + ": "); input = s.nextLine().replaceAll(" ", ""); System.out.println(input); for (int i = 0; i < input.length() - 1; i++) { row = Character.getNumericValue(input.charAt(i)); column = Character.getNumericValue(input.charAt(i + 1)); moves++; if (game.move(row, column, mark)) { game.printBoard(); if (game.validate(row, column, mark)) { System.out.println(mark + " has won. Game over."); break; } else { player = !player; } if (moves == 9) { System.out.println("The game is a draw."); break; } } else { System.out.println("Invalid move (taken or out of bonds). Try again."); } } } else { System.out.print("Enter row for player " + mark + ": "); row = s.nextInt(); System.out.printf("Enter column for player " + mark + ": "); column = s.nextInt(); moves++; if (game.move(row, column, mark)) { game.printBoard(); if (game.validate(row, column, mark)) { System.out.println(mark + " has won.
