Assistance with writing a tic tac toe program!

I'm new to java; I'm in my second Java collegiate course, and have to say am barely treading water. I have a project to create tic tac toe without a gui. Can anyone point me in the right direction of where to get some leads. Thanks!

Sure,

check out the tutorials at http://java.sun.com/docs/books/tutorial/index.html There are a ton of them. Let us know if you need any help along the way. Good luck

This is my potential Tic Tac Program without GUI; written in pseudo/java. If anyone could assist me with this I would greatly appreciate it!

package njohnsonp5;
import java.util.*;

public class NJohnsonP5Main 
{
    private char [][] board;
    private boolean xturn;
    private int numMoves;
    
    public static void main()
    {
        Scanner keyb = new Scanner(System.in);
        String response;
        
        do
        {
            NJohnsonP5Main game = new NJohnsonP5Main();
            play();
            System.out.println("Would you like to play 
                                       again?");
            response = keyb.nextLine();
        }while(response.equalsIgnoreCase("yes"));        
        
    }
    
    public NJohnsonP5Main()
    {
         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
    }
}

Looks good to me.

PS. Next time when posting make sure to use the [code][/code] tags. It makes it much easier to read. Thanks!

Thanks Destin, but I was looking for some assitance in writing the actual code where I have pseudocode.

I've also submitted my .java in the previous message.

Ah, sorry

. Well, what have you tried?

First of all, you'll need a board.

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

Then, you need to initialize the board.

Then, to check the winner, this gets a bit tedious.

Hope this helps a little. Post back if you're still having trouble.

So, I'm adding another array for another board. Add this to the board I have already?

And also, I know this might seem extra tedious, but my professor is anal, and he wants us to use his methods, so is there anyway you could alter the win method into my already won method?

I can't have a gui as well. He wants to see a old style tic tac toe bracket like

----|----|----

Thanks a bunch!

No, you only need one board. I'm just confused as to why you initialize your board with 5 by 5.

Why don't you give it a shot?

I believe it has to do with a manual tic tac toe screen as opposed to GUI.

I understand that there's no GUI. I just pictured it like this:

Would you know how to convert my public void play() method into actual java code?

Again, try it first, then ask for help. No one will not do it for you; we will only point you in the right direction.

So try it, if you're having problems, tell us exactly what you're having trouble with, what you don't understand.

Good luck!

Found this for you, it might help. But i suggest you to try it on your own. Just take this a reference.
