Help with Tic Tac Program

[Eric]

I have a project to create tic tac toe without a gui.
I need Assistance with writing a program.
Can anyone point me in the right direction of where to get some leads.
This is my potential Tic Tac Program without GUI; written in pseudo.

Code:

package proyect;
 import java.util.*;

 public class TicTacToeMain
 {
     private char [][] board;
     private boolean xturn;
     private int numMoves;
     
     public static void main()
     {
         Scanner keyb = new Scanner(System.in);
         String response;
         
         do
         {
             TicTacToeMain game = new TicTacToeMain();
             play();
             System.out.println("Would you like to play 
                                        again?");
             response = keyb.nextLine();
         }while(response.equalsIgnoreCase("yes"));        
         
     }
     
     public TicTacToeMain()
     {
          board = new char [5][5];
          xturn = true;
          numMoves = 0;
     }
     
     public void play()
     {
         do
         {
             //show board
             //get valid move
             //update board
             //determine winner if possible
         }while((no one has won)&&(moves < 9));    
     }
     
     public boolean won(int row, int col)//computer indices
                                                         (inside)
     {
         if(allSquaresInRowAreSame) or board[0][0]
            ==board[2][2]&&board[0][2]==board[0][4]
           return true;
         if(allSquaresInColAreSame)
           return true;
         return wonOnDiagonal();
     }
     
     public boolean wonOnDiagonal()
     {
         if(board[0][0]==board[2][2]&&board[2][2]
            ==board[4][4]&&board[0][0]!=space or " ")
             return true;
         return //same on positive and not space
     }
 }

Thanks!

Sure, check out the tutorials at The Java™ TutorialsThere are a ton of them.
Good luck.

First of all, you'll need a board.

Code:

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

I would recommend making final chars to represent what is in each sqaure.

Code:

private final char EMPTY = ' ';
 private final char PLAYER1 = 'X';
 private final char PLAYER2 = 'O';

you need to initialize the board.

Code:

 public void init() {
     for (int x = 0; x < 3; x++) {
         for (int y = 0; y < 3; y++) {
            board[x][y] = EMPTY;
         }
     }
 }

to check the winner, this gets a bit tedious.

Code:

public char winner() {
     for (int i = 0; i < board.length; i++) {
         /* check horizontally */
         if (board[i][0] == board[i][1] &&
                 board[i][0] == board[i][2]) {
             if (board[i][0] != EMPTY) {
                 return board[i][0];
             }
         }
         /* check vertically */
         if (board[0][i] == board[1][i] &&
                 board[0][i] == board[2][i]) {
             if (board[0][i] != EMPTY) {
                 return board[0][i];
             }
         }
     }
      
     /* check diagonally */
     if (board[0][0] == board[1][1] &&
             board[0][0] == board[2][2]) {
         if (board[0][0] != EMPTY) {
             return board[0][0];
         }
     }
     if (board[0][2] == board[1][1] &&
              board[0][2] == board[2][0]) {
         if (board[0][2] != EMPTY)) {
             return board[0][2];
         }
     }
     return EMPTY;
 }
