Tic - Tac - Toe Game - Please Help!
Hi everyone, I am attempting to create a tic - tac - toe game (O's & X's).
I would like there to be two playing modes to the game, the first mode will be one player where the user plays against the computer. The second mode is a two - player game, where two users play, one being X's and the other being O's.
Can anyone help me get started with this game, I know there is source code on the internet but I would rather not use this as I would like to learn as I create the game.
Thanks Everyoneits amazing how much code a simple game like tic-tac-toe can require.. well, only if you program the AI of the computer.. i wrote one in c++ last year, for my computer science class, and the whole class had trouble with it, mainly the AI.. a suggestion to you: write it in an object-oriented manner. i ended up writing it procedurally and in the end, it looked very bad, but it worked!
i would prob. setup some objects like: Board (the 3x3 grid), Mark (a user mark, such as an "x" or an "o")..
i dunno.. hope that helps some, if you need help with the AI at all.. i do have the tic-tac-toe program i wrote on my website (http://www.angelfire.com/blues/smb/ ) in the C++ section.. i used a graphics package, but the logic is all there and the code is well commented.
anyway, ill talk to ya later, good luck,

Need some help with Tic Tac Toe game
hey. hope u guys can help me out...
having a problem with my tic tac toe program...
i have 2 problems.
1) got the "X" and "O" to appear using a flag(teacher didn't explain)
using code like this
if (jb == button[0]){
if (flag==0)
button[0].setText("X");
else
button[0].setText("O");
//toggle
flag = (flag==0)?1:0;
my problem is how do i get it to stop.(For example button[1] is selected as "X"..how do i stop it from albe to switch to "O")
2) found this code in javascript online and i want to do what it does in java code
if(button[0] == " X " && button[1] == " X " && button[2] == " X ")
alert("You Win!");
reset();
how would i do that?
thanks for the help.ok here's my code:

Need help/advice with tic tac toe game
Hello all. I am working on a tic tac toe game. I was able to program the first 4 moves fine, but ame having trouble with moves 5 and 6 for reasons that are unknown to me. Everything complies fine, its just that the move is displayed int the wrong space (B1) instead of in B2 or B3. Also the move that is supposed to be in A1 disapppears when B2 or B3 is clicked. Also, I need advice as to how to keep the prior moves from being over written.
At this point I ahve gone over the code on-screen, printed it out, and stared at my drawings... and I'm not having any luck. I'm sure its a small, stupid thing that I'm missing, that anyone else would easily catch. Once again, thx for all your help.

//<applet code = "game3.class" height =300 width=300> </applet>writing a tic-tac-toe is harder than it sounds.. i wrote one last year in my computer science class.. i have it on my website, if you want to look at code. i wrote it in c++, but the logic is all that matters :)
btw-last year, i wasnt too good of an OOP programmer, so the program is procedurely written. heres the url:
http://www.angelfire.com/blues/smb
also, to tell if a box is already taken, you can just add an if statement: if ( gameBoard[selX][selY] == null ) //not taken, fill box:many people resort to a boolean matrix of the same idea, but with booleans that store which boxes are taken. i prefer the way above, saves code, memory, and makes it more understandable.
hope it helps. -
Does anyone know of an open-source implementation of Tic-Tac-Toe using Graphs? I'm reading through Michael Mann's Data Structures and Other Objects Using Java book and in chapter 14, he briefly mentions the use of directed graphs in implementing a game of Tic Tac Toe. I'm interested in seeing how one would implement something of this sort (and no, it's not a homework assignment).
If someone would be kind enough as to post a link to a site that offers mini-java applications, along with code that novice developers such as myself can traverse, please do so.
Thanks in advance.As an added though, there's really no need to for each node to keep track of incoming connections, only outgoing ones. What I, personally would do is keep an array of 8 outgoing connections, one for each direction. If no connection was there, then that element in the array would be null. If a connection was there, then that element would be an edge connecting to another node, or the other node itself (depending on whether or not you explicitly implemented 'edges' in your graph).
That way, you could do something like:
Node s = getOneOfTheEdgeNodes();
boolean hasWinner = false;
try {
for (int i = 0; i < 8; i ++) {
if (s.getOutgoing(i).getNode().getOutgoing(i).getNode() != null) {
hasWinner = true;
break;
} catch (NullPointerException npx) {
// No winner.
if (hasWinner)
System.out.println(s.getPlayer() + " has won");Yeah, that's a shitty example, but hopefully you get my drift.

Test out this Tic Tac Toe game please
I know this is suppose to be a real java forum, but this is stripped down version of java, but it's still java. Before using real java I used this Judo. So can you guys download the stuff and play it a few times. Give me any suggestions or bug reports. This is v. 1.0 and there isn't a winner decider yet. Thanks and hope you have fun!
You will need to download JUDO
http://judo.sourceforge.net/#download
Open JUDO and paste this code into it and run.

I have finished my entire game excpet for who wins. Anyone have some insight on how to do this?
private boolean isRow(char arr[][],char s)
for (int i=0;i<3;i++)
if (arr[0]==arr[i][1] && arr[i][1]==arr[i][2])
if (arr[i][0]==s)
return true;
if the condition if (arr[0]==arr[i][1] && arr[i][1]==arr[i][2]) was false so return true; won't work, and so the method is left without a return value.
you can solve the problem by modifying this code to this:
private boolean isRow(char arr[][],char s)
for (int i=0;i<3;i++)
if (arr[0]==arr[i][1] && arr[i][1]==arr[i][2])
if (arr[i][0]==s)
return true;
return false; -
Hit there!!
Does anyone know where can I find exaples of applications whith that game?
I've seen them somewhere that I cannot remember.
Thanks in advance

1) What specific problems you're having.
2) Relevant code.
iam unable to attach the code now;So, you call the doctor on the phone, say, "I'm not feeling well. Please make me better. I can't come to your office or tell you anything about what's wrong with me now." -
Help in swing app. tic tac toe
Trying to make this tic tac toe game. Need a little help. I want the newGameBUT to start the game over, and I would like turnTF to display if a tie occurs. (I tried using *if button.enabled(false) {* but it didn't work. If anyone could help me out, that'd be great. Oh, also, the new game button currently add's 1 to whoever won so far, which is really weird =x. Thanks beforehand.

I need help on a Tic Tac Toe game I am making for a class. I had finished a "2 Player" version and my instructor wants me to simulate a computer "AI" now. I cannot figure out what I'm doing wrong. The order of precedence is this:
1. X moves first (the player)
2. Computer moves to win.
3. If it can't win, it moves to block a win
4. If it can't block a win, it moves to the best possible spot to set up a win.
I think my problems are with several methods, but I cannot figure out what I'm doing wrong. Every time I look at my code, it just makes "sense". I think my problems could probably be found in 4 methods, setButtonText(), findOpen(), findBestOpen() and tempCheck(). I would like hints or maybe if I could get a second look at it for me.

I click to make "X"'s (the player's move). X appears but O never does, although a button is highlighted. If I keep pressing the buttons, all X's appear until the last move, when an "O" appears.I don't know if it's the problem, but
checkWinner("0");looks suspicious. (2nd invocation in your tempCheck() method).
Your program seems awfully brittle. How would you do it if you had a 4 x 4 board? Or 5 x 5?
Also, your 'winningCombos' array is repeated everywhere it's used. There's no need for that; just make it an instance variable/constant.

Well I'm getting ready for my second semester of Java programing and I figured I would try and get back in the swing (no pun intended) of things by creating a simple tic tac toe game. I was able to make a two player game with in a matter of hours so I figured I would try and make a one player game with AI and thats where im having some issues. Here is my code for two person tic tac toe
package mytictactoe;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TicTacToeV2 implements ActionListener {
/*Instance Variables*/
private int[][] winCombinations = new int[][] {
{1, 2, 3}, {4, 5, 6}, {7, 8, 9}, //horizontal wins
{1, 4, 7}, {2, 5, 8}, {3, 6, 9}, //virticle wins
{1, 5, 9}, {3, 5, 7} //diagonal wins
private JFrame window = new JFrame("Tic-Tac-Toe");
private JButton buttons[] = new JButton[10];
private int count = 0;
private String letter = "";
private boolean win = false;
public TicTacToeV2(){
/*Create Window*/
window.setSize(300,300);
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setLayout(new GridLayout(3,3));
/*Add Buttons To The Window*/
for(int i=1; i<=9; i++){
buttons[i] = new JButton();
window.add(buttons);
buttons[i].addActionListener(this);
/*Make The Window Visible*/
window.setVisible(true);
public void actionPerformed(ActionEvent a) {
count++;
/*Calculate whose turn it is*/
if(count % 2 == 0){
letter = "O";
} else {
letter = "X";
/*Write the letter to the button and deactivate it*/
for(int i=1; i<=9; i++){
if(a.getSource() == buttons[i]){
buttons[i].setText(letter);
buttons[i].setEnabled(false);
/*Determine who won*/
for(int i=0; i<=7; i++){
if( buttons[winCombinations[i][0]].getText() == buttons[winCombinations[i][1]].getText() &&
buttons[winCombinations[i][1]].getText() == buttons[winCombinations[i][2]].getText() &&
buttons[winCombinations[i][0]].getText() != ""){
win = true;
/*Show a dialog when game is over*/
if(win == true){
JOptionPane.showMessageDialog(null, letter + " wins the game!");
System.exit(0);
} else if(count == 9 && win == false){
JOptionPane.showMessageDialog(null, "The game was tie!");
System.exit(0);
public static void main(String[] args){
TicTacToeV2 starter = new TicTacToeV2();
Now for my program with AI I'm essentially using the same code and just for clarity I removed all the code that determines who won (as it isnt needed to get the AI to work) This is what I have so far
package mytictactoe;
import java.awt.*;
import java.awt.event.*;
import java.util.Random;
import javax.swing.*;
public class TicTacToeV3 implements ActionListener {
/*Instance Variables*/
private JFrame window = new JFrame("Tic-Tac-Toe");
private JButton buttons[] = new JButton[10];
private int count = 0;
public TicTacToeV3(){
/*Create Window*/
window.setSize(300,300);
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setLayout(new GridLayout(3,3));
/*Add Buttons To The Window*/
for(int i = 1; i<=9; i++){
buttons[i] = new JButton();
window.add(buttons);
buttons[i].addActionListener(this);
/*Make The Window Visible*/
window.setVisible(true);
public void actionPerformed(ActionEvent a) {
count++;
/*Write the letter to the button and deactivate it*/
for(int i = 1; i<= 9; i++){
if(a.getSource() == buttons[i]){
buttons[i].setText("X");
buttons[i].setEnabled(false);
AI();
public void AI(){
Random x = new Random();
int y = 1 + x.nextInt(9);
if(buttons[y].getText() == "X" || buttons[y].getText() == "O" ){
AI();
} else {
buttons[y].setText("O");
buttons[y].setEnabled(false);
public static void main(String[] args){
new TicTacToeV3();
It kind of works because each time i choose a box the "computer" also chooses one, but since it is so random the chances the computer wins is very limited. I then tried to do something like this in the AI() method and it seems to be on the right track but once one of the if's are satisfied the all the AI logic stops
public void AI(){
//horizontal AI defencive code
if(buttons[1].getText().equals(buttons[2].getText()) && buttons[1].getText() != ""){
buttons[3].setText("O");
buttons[3].setEnabled(false);
} else if(buttons[2].getText().equals(buttons[3].getText()) && buttons[2].getText() != ""){
buttons[1].setText("O");
buttons[1].setEnabled(false);
} else if(buttons[4].getText().equals(buttons[5].getText()) && buttons[4].getText() != ""){
buttons[6].setText("O");
buttons[6].setEnabled(false);
} else if(buttons[5].getText().equals(buttons[6].getText()) && buttons[5].getText() != ""){
buttons[4].setText("O");
buttons[4].setEnabled(false);
} else if(buttons[7].getText().equals(buttons[8].getText()) && buttons[7].getText() != ""){
buttons[9].setText("O");
buttons[9].setEnabled(false);
} else if(buttons[8].getText().equals(buttons[9].getText()) && buttons[8].getText() != ""){
buttons[7].setText("O");
buttons[7].setEnabled(false);
} else {
Random x = new Random();
int y = 1 + x.nextInt(9);
if(buttons[y].getText() == "X" || buttons[y].getText() == "O" ){
AI();
} else {
buttons[y].setText("O");
buttons[y].setEnabled(false);
}And basically what that does is it checks if I have two X's in a row horizontally, If I do it will place an O in the box preventing me from getting three in a row (only in horizontal rows). Of course I would iterate this over and over for all possible combinations of offensive moves and defensive moves and probably do it using a for loop but this is just some scratch code I threw together to show you my thoughts. And again my problem is once one of the conditions are satisfied it never checks the conditions again and I'm not sure why that is...
So I'm looking for some ideas and/or some pseudo code to help me out a little.
ThanksWell I did this and its a step closer to working but there is another bug and all this logic is hurting my head. Again lets say my grid is numbered like this
1 | 2 | 3
4 | 5 | 6
7 | 8 | 9
If I go 1, the computer will randomly pick a square thats not set. Lets say the computer picks 4. Now I pick 5 and the computer picks 9 because I would earn 3 in a row diagonally. Then I pick 2 and I can now win three in a row 2-5-8 or 1-2-3. The computer picks 3 because that logic is earlier in the code. BUT when I press 8 to to take the win, but the computer cheats and labels my button thats supposed to be an X as an O, so it should look like this:
X | X | O
O | X | 6
7 | X | O
but it does this
X | X | O
O | X | 6
7 | O | O
Here is the AI logic part (its mostly repetitive)
public void AI(){
/*Defencive Moves*/
//horizontal defencive possabilities
if((buttons[1].getText() == "X")&&
(buttons[2].getText() == "X")&&
(buttons[3].getText() != "O")){

What am I doing wrong? -
Tic-Tac-Toe [ What would you do different? ]
I was bored so I made a simple 2-player tic-tac-toe game. I was just wondering if there was any room for improvement [other than the lack of comments]
package tictactoe;
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class TicTacToe {
private char[] board = new char[] { '1', '2', '3', '4', '5', '6', '7', '8', '9'};
private int count = 0;
private int location;
private int[][] winCombinations = new int[][] {
{0, 1, 2}, {3, 4, 5}, {6, 7, 8}, //horizontal wins
{0, 3, 6}, {1, 4, 7}, {2, 5, 8}, //virticle wins
{0, 4, 8}, {2, 4, 6} //diagonal wins
private InputStreamReader isr = new InputStreamReader(System.in);
private BufferedReader br = new BufferedReader(isr);
private boolean win = false;
public TicTacToe(){
while(checkWin() != true && count < 9){
displayBoard();
getInput();
setLocation();
count++;
endGame();
public void displayBoard(){
System.out.println( board[0] + " | " + board[1] + " | " + board[2]);
System.out.println("---------");
System.out.println( board[3] + " | " + board[4] + " | " + board[5]);
System.out.println("---------");
System.out.println( board[6] + " | " + board[7] + " | " + board[8]);
System.out.println("\n");
public void getInput(){
System.out.print("Enter the location on the board: ");
try {
//Convert the string to an integer
location = Integer.parseInt(br.readLine());
} catch(Exception Error) {
System.out.print("You have entered an invalid number. You must enter a number between 1 and 9 inclusive. Try again.\n\n");
getInput();
if(location < 1 || location > 9){
System.out.println("You must enter a number between 1 and 9 inclusive. Try again.\n\n");
getInput();
public void setLocation(){
if(count % 2 == 0)
board[location-1] = 'X';
else
board[location-1] = 'O';
public boolean checkWin(){
for(int i=0; i<=7; i++){
if( board[winCombinations[0]] == board[winCombinations[i][1]] &&
board[winCombinations[i][1]] == board[winCombinations[i][2]]){
win = true;
return win;
public void endGame(){

displayBoard();
System.out.println("The game is tie!");

Thanks.1. disassociate any program logic from UI so that it
can easily be ported to a GUI such as swing>
As for 1, are you talking about the getInput method?
Thats the only method that associates logic with UI
as far as I'm concerned and when it is ported into a
GUI, the user wont have the ability to select a
square out of range so that logic wont even exist. Is
there any other?What I mean is can you take the core logic portion of your code and easily plug it directly to your GUI code or non-GUI code or even changed different GUI code. This can occur if the logic portion is so well encapsulated that it doesn't depend at all on the user interface. another way to put it is the core functionality of the program should not reside in the GUI class (or classes).
Admittedly w/ 2-D tictactoe, this may not be quite so relevant.
addendum: check out Model-view-controller on wikipedia.
