Computer AI for Tic-Tac-Toe
Hi, I'm pretty new to java. I've taken some classes but I don't know much. I am trying to create a Tic-Tac-Toe application and I want to create a computer that will play all the correct moves and never lose. I'm not finished with the moves that the computer makes. I've tagged where I'm having the problems. Here it is:package mytictactoe;
import java.awt.*;
import java.awt.event.*;

import javax.swing.*;

Here is updated code, that I believe will not be beatable by human input. Let me know if you find any bugs.

Hi, I'm brand new to your website this is my first post. I am currently in a Computer Science class and extremely new to Java. Our teacher gave us an assignment in Java (Eclipse) for Tic Tac Toe. I have the interface built already with Player One being X's and Player Two being O's and everything seems to work out but I have a major problem. When I get a player with 3 in a row I need a line to pop and for a message signify the winner. I have absolutely no idea on how to do this. So if there is anyone out there that would like to give me some guidance I would be greatly appreciated. I will just post my code below. Thank you very much.

When I get a player with 3 in a row I need a line to pop and for a message signify the winner. Use a JOptionPane. Read the JOptionPane API and you will find a link to the Swing tutorial on "How to Use Dialogs". -

</code>Yeah Thanks.
So I'm just stuck here. Like I need to program a Tic Tac Toe GUI with the X's and O's as images but I have no clue on what to do next. I have the images for both but I don't know how to make them work once the buttons are clicked.
Sorry here it is again..

vamshijupallyi have written the code for tic-tac-toe game
partially.i am stuck at writing the code for "who is
the winner"? and adding a button to start the new
game ?please help me out to write the remaining?That question is almost impossible to answer because you didn't provide two vital pieces of information.
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." -
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.

Help with Tic Tac Toe program....
I am writing a tic tac toe program, and I have already put the 9 boxes onto the screen so that it looks like the Tic Tac Toe board.
My first box looks something like this:
Rectangle2D.Double box1 = new Rectangle2D.Double(0, 0, 100, 100);
g2.draw(box1);
I want assign a number to the 9 boxes so it looks like this:
123
456
789
And I want to know how am I suppose to assign a number to a box, so that when the number is pressed it will put an "X" or "O"(depending on whose turn it is).
P.S. If you already made a Tic Tac Toe progaram can you post it so I will have an idea of what you did. thx.I'd hate to post the whole thing, but if you don't have access to it, here it goes:

hey all,
i am having problems creating a tic tac toe program. the program should create a board with NxN spaces, where N is obtained through user input.
I created a fully working program that does a 3x3 board, checks for diagonal, vertical, horizontal wins and also allows 1 vs computer or 2 players play, but i am struggling with the NxN board.
here is the code of what i have, can anyone point me in the right direction? all help is appreciated! please keep it simple as possible as i am just learning java!!

playHuman();well, i figured out how to do it all, thanks to the TREMENDOUS amount of help here...lol...
i just have one more (minor problem)...
i can't get an algorithm working to see if the two diagonals are occupied by x's or o's (see if someone won diagonally)
to check horizontally & vertically on an NxN board, i use following code:
int count = 0;
/** check horizontally */
for (int i = 0; i < myBoard.length; i++)
for (int j = 0; j < myBoard.length-1; j++)
if (myBoard[0].equals(myBoard[i][j+1]) && !myBoard[i][0].equals(EMPTY))
count++;
if (count >= myBoard.length-1)
return myBoard[i][0];
count = 0;
count = 0;
/** check vertically */
for (int i = 0; i < myBoard.length; i++)
for (int j = 0; j < myBoard.length-1; j++)
if (myBoard[j][0].equals(myBoard[j+1][i]) && !myBoard[0][i].equals(EMPTY))
count++;
if (count >= myBoard.length-1)
return myBoard[0][i];
count = 0;
now i was messing around ALOT and couldn't figure out how to get the diagonals showing! this is what i came up with:
count =0;
for (int j = 1; j < myBoard.length; j++)
if (myBoard[0][0].equals(myBoard[j][j]) && !myBoard[0][0].equals(EMPTY))
count++;
System.out.println(count);
if (count >= myBoard.length)
return myBoard[0][0];
count = 0;
for (int j = myBoard.length-1; j >= 0; j--)
if (myBoard[0][myBoard.length-1].equals(myBoard[j][j]) && !myBoard[0][myBoard.length-1].equals(EMPTY))
count++;
System.out.println(count);
if (count >= myBoard.length)
return myBoard[0][myBoard.length-1];
count = 0; -
Hi,
i am trying to create the tris game in java (maybe you know this game as tic tac toe). I created windows and the alghoritm to play. But now i have the problem to create the board. My idea is to create a board with nine clickable cells, the player clicks on the cell he wants (if it's free), then the computer plays and so on...but i don't have the knowledges of making complex graphic things in java. How can I do?ok, and how can i manage the player's click?MouseListener on the JLabel.
remember
also that when the player clicks, the program must
draw a symbol (x or o depending from the choice of
player). how can i do all this things? For a noob
like me this is very difficultRead the tutorials. I'm not going to explain to you how to create your app if you can read it up yourself. -

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. -
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,
Steven Berardi -
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)

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.

A Tic Tac Toe board is represented as an array of 9 chars. Write a program that will allow two users to play tic tac toe. The player should ask for moves alternately from players X and O. The program is too dumb to check whether anyone has won or lost and just stops after 9 turns. The program should display the game position as follows after each move.
The output should be somewhat as follows:
Choose a spot (1 to 9) for X: 1
X || ||
|| ||
|| ||
Basically i have to do this. I was wondering if anyone could lead me in the right direction please?class TicTacToe {
// instance variables
// constructor(s)
// method(s)
public static void main(String[] args) {
new TicTacToe();
}There you go. I got you started. Now all you need to do is finish.

64 bit HP drivers don't work reliably over a network
Running Win 7 64 bit clients, and server 2008. HP's own drivers are very unreliable. Printers work ok for a while, and then for no reason start outputting garbage. Changing print driver to universal sometimes resolves the issue for a time, but garbag
