Tic Tac Toe Java help!
Hi, I have been trying to create a simple Tic Tac Toe game using Java. I'm currently having problems as to how to create the board using arrays (sorry I don't understand them very well). All I have so far is this,
public class ticTacToe {
private int [] [] theBoard = new int [3] [3];
// *'N' is no winner
// 'X' is X won
// 'O' is O won
// 'C' is a cat's game
public static char didSomeoneWin(int [] [] currentBoard)
int winForX = 8000, winForO = 1, checkIfItsAcatsGame = 1, product;
char winner = 'N';
for(int column = 0; column < 3; column++) // Check the columns
product = currentBoard [0] [column] * currentBoard [1] [column] * currentBoard [2] [column];
if(product == winForX) winner = 'X';
if(product == winForO) winner = 'O';
for(int row = 0; row < 3; row++) // Check the rows
product = currentBoard [row] [0] * currentBoard [row] [1] * currentBoard [row] [2];
if(product == winForX) winner = 'X';
if(product == winForO) winner = 'O';
product = currentBoard [0] [0] * currentBoard [1] [1] * currentBoard [2] [2]; // Check one diagonal
if(product == winForX) winner = 'X';
if(product == winForO) winner = 'O';
product = currentBoard [0] [2] * currentBoard [1] [1] * currentBoard [2] [0]; // Check the other diagonal
if(product == winForX) winner = 'X';
if(product == winForO) winner = 'O';
if(winner == 'N') // If nobody's won, Check for a cat's game
for(int row = 0; row < 3; row++)
for(int column = 0; column < 3; column++)
checkIfItsAcatsGame *=currentBoard [row] [column];
if(checkIfItsAcatsGame != 0) winner = 'C'; // any empty space is a zero. So product is zero if there is space left.
return winner;
public void markX(int row, int column)
myBoard [row] [column] = 20;
public void markO(int row, int column)
myBoard [row] [column] = 1;
That is all so far, could someone help me print out the board? And help me out on the arrays? I don't think they are quite right. Thanks in Advance!

Hi,
Do you need a GUI ?
If yes see http://java.sun.com/docs/books/tutorial/uiswing/index.html
You can also see this : http://www.apl.jhu.edu/~hall/java/Swing-Tutorial/Swing-Tutorial-Printing.html about printing.

Basic Tic Tac Toe programming help please
I'm trying to make a seperate java class(there is another main that calls this using SWING interface) that makes mark on the board.
It's supposed to do the following
Method makeMark returns:
a null if the cell indicated by row and column has already been marked
an X if it is X's turn (X gets to go first)
a Y if it is Y's turn
Thus makeMark will have to keep of marks made previously and return the appropriate string
for the requested cell.
and here is what I got so far, but only getting empty clicks as a respond. Any help will be appreciated. thanks.
import javax.swing.JButton;
public class TicTacToeGame {
public String makeMark(int row, int column){
String player = "X";
String [][] Enum = new String [3][3];
for (row=0; row<=2; row++){
for (column=0; column<=2; column++)
if (Enum[row][column] == "")
if (player == "X"){
Enum[row][column] = "X";
player = "Y";
return "X";
if (player == "Y"){
Enum[row][column] = "O";
player = "X";
return "Y";
else
return null;
return player;
}ok is there a simpler codes that will just flip-flop between X and O? I had it working before but somehow it's not working anymore. Before I had
public String makeMark(int row, int column){
player = "X";
if (player = "X")
player = "O";
else if (player = "O")
player = "X";
or soemthing like this but it used to work, but I had to revise the code to do more things and it stopped even flip-flopping between X and O.
Here's main code:

Im making a tic tac toe game and everything works fine until you try to click the third set of blocks in order to put your X or Y in it. The program does nothing, it even seems as if the mouseDown function isnt working.......can someone help (Code below)

public class TicTacToe extends Applet {
int test = 0;
int test1 = 0;

int temp;
char square[][];
protected int turn;
final int width = 117;
boolean TurnP1;
boolean TurnP2;
public void init() {
square = new char[3][3];
for(int i = 0; i < 3; i++) {
for(int j = 0; j < 3; j++) {
square[i][j] = 0;

public boolean mouseDown(java.awt.Event e, int x, int y) {
int column = (int)(x / (width / 3));
int row = (int)(y / (width / 3)+1);
test = column;
test1 = row;
turn++;
if (square[column][row] != 0) {
play(getCodeBase(), "beep.wav");
if (TurnP2) {
turn = 4;
} else {
turn = 3;
return true;
if (turn % 2 == 0) {
//Its Player 2 turn
TurnP1 = false;
TurnP2 = true;
square[column][row] = 'O';
} else {
//Its Player 1 turn
TurnP1 = true;
TurnP2 = false;
square[column][row] = 'X';
repaint();
return true;the method you use should not be overridden without a call to the ancestor like:
public boolean mouseDown(Event e,int x,int y){
super.mouseDown(e,x,y);
//your code here
}it is more safe.but anyway the best thing to do what you want is to use:
public MyApplet extends Applet implements MouseListener {
public init(){
addMouseListener(this);
//methods mouseReleased,...
public void mouseDown(MouseEvent e){ -
Tic tac toe pls help! there is clarification
How can i build a tic tac toe game in labview
What im interested in is the following, and ive added an image of what the front panel should look like with some clarification
1) A 3x3 multiplayer game
2) A boolean to move left in the tictactoe grid and another to move down
3) A boolean array to display the grid an another string array to show the X and O's
4) A boolean to confirm player's choice
5) A way to choose whether player 1 or player 2 begins
6) A way to show which player wins or loses, or if it is a draw.
Thank You in Advance
I appreciate your help !!

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.

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; -

the error message says that I still need a "}" on line 49 which is the line after the last bracket that I have, I put one there and it still shows up an error message, what do I do? -
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!");

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

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 problem please help
hi,
My program consists of 4 classes but working bit by bit and currently using 2 classes. I've managed to get an 'X' to appear on the grid but I'm having problems arranging it like a tic tac toe grid and another number appears under the number selected by the player next to the grid, how do i get rid of it?? the output is like this.........
// output
Enter player's Name:
Name:
dave
dave to play
Enter move by selecting number from grid, or 0 to draw
Move entered:
1
1 0X23456789
it also says "String index out of range:-1 any ideas what this means?????
heres my source code for the program....
//Main program
public class TheTest1
public static void main( String [] args)
TheTest TT = new TheTest();
TT.gridSheet("0123456789", true);
// TheTest
import element.* ; // import the package that contains
// the ConsoleWindow class
public class TheTest
String name1;
String turn;
int cell, move;
final static char NOUGHT='O', CROSS='X';
public TheTest()
c.out.println("Enter player's Name:");
c.out.println("Name:");
name1 = c.input.readString();
turn = name1;
move();
public void move()
if(turn.compareTo(name1)==0)
c.out.println(name1 + " to play");
c.out.println("Enter move by selecting number from grid, or 0 to draw");
c.out.println("Move entered: ");
cell = c.input.readInt();
public void gridSheet(String fruit, boolean play)
for(int j = 1; j<9; j=j+3)
char index;
for(int i = j; i<(j+3); i++)
if(play==true)
index = fruit.charAt (i);
c.out.print (index + " ");
//index = fruit.charAt(i);
if(cell==1 && turn.compareTo(name1)==0)
cell=fruit.indexOf('1');
fruit=fruit.substring(0,cell) + CROSS + fruit.substring(cell+1);
c.out.println(fruit);
//move();
//c.out.println(" ");
Any help will be appreciated.
Many thanks
Davethis is a tic tac toe console and you're having trouble displaying it as a grid?
if so, this is one way to simulate the board (some of the code is just for display in this example)

String[] board = new String[9];
public TicTacToeConsole()

try{playGame();}catch(Exception e){e.printStackTrace();}
public void playGame() throws IOException
System.out.println("Board at game start");
printBoard();
System.out.println("\nPlease select an available number to put your X");
printAvailableSquares();
int playerMove = Integer.parseInt(input.readLine()) -1;
board[playerMove] = " X ";
System.out.println("\nBoard after first move");
printBoard();
System.out.println("\nAvailable moves after first move");
printAvailableSquares();
public void printBoard()
System.out.println();
for(int x = 0; x < board.length; x++)
System.out.print(board[x]);
if(x%3 == 2) System.out.println("\n");

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.

{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.
