Question

I’m creating a simple Tic Tac Toe game. I’ve declared my 3 by 3 board and initialized each play area to ' ' or a space character.

However, when I try to print the board so that I get something that looks like this:

   1   2   3
A    |   |    
   ----------
B    |   |   
   ----------
C    |   |   

Nothing gets printed.

Here is my TicTacToe.java:

import java.util.Scanner;

public class TicTacToe{

    public static void main(String[] args) {
           new TicTacToe();
    }
    private char[][] board;
    private char player;

    public TicTacToe() {
    for(int i = 0; i < 3; i++)
    {
        for(int j = 0; j <3; j++)
         {
           board[i][j] = ' ';
         }
    }
     player = 'X';

    System.out.println(" 1 2 3");
    System.out.println("A" + board[0][0] + "|" + board[0][1] + "|" + board[0][2]);  
    System.out.println("-----");
    System.out.println("B" + board[1][0] + "|" + board[1][1] + "|" + board[1][2]);  
    System.out.println("-----");
    System.out.println("C" + board[2][0] + "|" + board[2][1] + "|" + board[2][2]);                        
    }

I’ve read from Murach’s 4th edition that when the class is executed, the constructor is executed as well so I assume that the print functions will be executed.

Question:

How do I print my tic tac toe board like the one above to my console?

Edit:
Thank you for the help. Turns out I had to call the constructor instead of it automatically being executed. Code above does not contain the solution.

Answer 1

I have made some changes in the code

public class TicTacToe {

    public static void main(String[] args) {
        new TicTacToe();
    }

    private char[][] board = new char[3][3];
    private char player;

    public TicTacToe() {
        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 3; j++) {
                board[i][j] = ' ';
            }
        }
        player = 'X';

        System.out.println(" 1 2 3");
        System.out.println("A" + board[0][0] + "|" + board[0][1] + "|"
                + board[0][2]);
        System.out.println("-----");
        System.out.println("B" + board[1][0] + "|" + board[1][1] + "|"
                + board[1][2]);
        System.out.println("-----");
        System.out.println("C" + board[2][0] + "|" + board[2][1] + "|"
                + board[2][2]);
    }
}

Hope this will help you.
