Thread: tic tac toe single array code help

Hi. I am having trouble writing the code to create a tic tac toe game using a single array. I don't know where to start with getting the rest of the code to work. Can anyone please help me.

This is my code so far:

///*
 
*/
 
import java.io.*;
 
public class H2_tictactoe
{
   public static void main(String args[]) throws IOException
 
    {
 
       String welcome = "Welcome to Tic Tac Toe Player 1\n";
         char[] board = {0, 0, 0, 0, 0, 0, 0, 0 ,0};
 
 
         String inputPlayer;
         char movesArray;
         char player1 = 'X';
         char player2 = 'O';
 
 
 BufferedReader dataIn = new BufferedReader(new InputStreamReader(System.in));
 
        movesArray = 9;
 
 {
 
}
 
showboard(board);//Call method showboardGame
    menu();//Call method menu
inputPlayer = dataIn.readLine(); //read in input from player
 
 
 
}
 
public static void showboard(char theboard[])
 
{
        System.out.println("------------");
        System.out.println(" 0| 1 | 2 ");
        System.out.println("------------");
        System.out.println(" 3| 4 | 5 ");
        System.out.println("------------");
        System.out.println(" 6| 7 | 8 ");
        System.out.println("------------");
        System.out.println("");
}
 
public static void menu()
    {
          System.out.println("Choose the number associated with the space where you want to move:");
          System.out.println("0. Space 0");
          System.out.println("1. Space 1");
          System.out.println("2. Space 2");
          System.out.println("3. Space 3");
          System.out.println("4. Space 4");
          System.out.println("5. Space 5");
          System.out.println("6. Space 6");
          System.out.println("7. Space 7");
          System.out.println("8. Space 8");
}
 
{
 
 
}
}

First of all, could you surround your code in highlight tags please? Do so like this:

[highlight=Java]//your code here[/highlight]

Secondly, I don't know how to help you because I don't know what the code does so far. Does it work, or are there errors? If there are, could you post them? Otherwise, are you stuck on making a GUI? Code logic? Please be more specific.

Okay. You have an array of characters to store what moves are made where, so next maybe have the program check the value of the array at the index the user specified (make sure that spot isn't already occupied), and if the move is valid, set the value of the char[] at the index to that user's symbol (player 1 = x, player 2 = o, as I think you had it).

As for displaying the board, I'd make a method that checks the value of the char[] and puts in the correct symbol (or nothing) based on the values. That way, you can call the method whenever you need. So, you'd basically just need to change your showboard() method so that it actually DOES something with the char[] you put in (use if statements!).

Note, you should probably also create a method that checks if either user has won, and then wrap everything in a loop. So, have some structure like this:

while(!playerHasWon()) //playerHasWon() would be a method you'd write
{
   showBoard(board); //your char[] board
   //Do stuff to get input
   showBoard(board); //show board again for player 2
   //Do stuff for player 2 input
}

That would be the general flow I would use for this program.
