Tic Tac Toe with AI
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.
Thanks
Well 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(){

Hello,
I am working on a Tic Tac Toe game, I have already started woking on it put i am
stuck on the array part. This is what is required in the project: Create a nine-member array to hold results of the game.. Initialize the array before the start of the game...Allow the user input to indicate which square ther user selects...

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!!

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; -
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?

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. -
Help with printing a tic tac toe board (using a loop to print)
hey im making the smiple game tic tac toe and im tryin to print out the board after each turn. I have a 2d array called char which is a 3 by 3 array and i dont know how i would make a for loop to print out the x's and o's in their right spot and still have the board look like a normal tic tac toe board. When the board is printing the x's and o's are already in the 2d char array board.So basically what i want to happen is after player 1's turn is up wherever he put the x replace the number on the board with an x and keep the rest the same and whenever player 2's turn is up wherever he put the o replace the number on the board with an o and keep the rest the same. Any help would be awesome thanks alot.
Here is the code to the program (i know i use if statements to much its a bad habit of mine)
import java.util.*;
public class Tictactoe
private char board [] [] = new board [3] [3];
private int X;
private int O;
private Scanner p1choice;

{Anyway the answer is that you are trying to create an array of char as there is no such thing as a board[3][3].
One of the best tools a programmer can do is learn how to break a big problem into little problems and work on each little problem in isolation, and then when finished combining the solutions together into the final program. You big mistake that I see here is trying to bite off more than you can chew: trying to create a whole functioning interactive program from just one class. Why give yourself a task that would be difficult even for an experienced java programmer? I suggest that you break this down into logical parts and try to solve the smaller problems before worrying about the whole. For instance, if I were doing something like this, I'd create a class called TTTBoard that encapsulated the tic tac toe board and nothing but the board. I'd think of it as an entity. When I wanted the current state of the board, I'd query the board via a method such as getCurrentState. I'd have methods for checking if position is free, for placing an x/o in a spot, for checking for win, etc... Then I'd create a user interface class where I'd give the users a choice and get their responses. I'd probably create a Game class to control it all. While this all seems daunting, you are trying to do essentially the same thing, but all in one huge class. My recommendation: study OOPs and learn to do it the smart way. Good luck. -
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.

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. -
Why do I keep getting the following errors in a very simple, basic TIC TAC TOE program? Any help would be greatly appreciated. Thanks.

System.out.println();the "else without if" means that you have an else statement that wasn't attached to an if statement. In your case, it seems to be because you had multiple statements following an if statement, and you didn't enclose them in a single block.
The "cannot resolve symbol" means that you referred to something that wasn't defined. Either it's your code, and you forgot to define it, or you were referring to someone else's code, in which case you probably forgot an import statement, or you're using their code incorrectly. -
I wrote a Tic tac toe program in net beans aka Java and i wanna know how to get it on my geocities website.
P.S
There are 10 dukes dollars assigned, help would be appreciatedOtherwise I could become dramatically de-incented.Yes, student85, and what about poor Laszlo in thread http://forum.java.sun.com/thread.jspa?threadID=5170840
He's an old man who walks with a cane and you can't spare him a duke! -
If anyone has any interest, please look at this code and tell me what is wrong with it.
It is supposed to play tic tac toe perfectly, it does not.
I attempted to use the negamax algorithm.
Please post any specific changes you made.
Thanks./* This doesn't seem to work, there is always at least 1 cmd line arg for some reason
if (argc != 0)
{ printf ("WARNING: %d command line arguement(s) ignored!n", argc); }
else
{ printf ("TEST"); }
The reason why there is always at least one command line argument is because the name of the executable is counted.
For example, if you ran your program like this:
./tic-tac-toe foo bar
Then:
argc == 3
argv[0] == tic-tac-toe
argv[1] == foo
argv[2] == bar

Hey, so I've completed all the basic steps for playing the actual game, but now I'm working on creating the final booleans for determining if someone won or if it's a stalemate. Here's my entire code, but the boolean methods of interest are located at the bottom. Do I just use the player variable for the if statements? Am I missing anything? Thanks in advance.

}Sorry about the ugliness - no it doesn't do what I want it to yet - I would just like some assistance with the public boolean won() method. The game doesn't end when a real life winner is determined. So, if we could just start with that, that'd be great. Thanks.
