TicTacToe help
I am using Netbeans 4.0 to create a midlet app. The problem is that when I compile it tells me that java.text does not exist and I have a problem with Java.io. I will post code and output. PLEASE HELP!!!

Help needed on a TicTacToe java program
I am very new to java and our teacher has given us a program
that i am having quite a bit of trouble with. I was wondering if anyone could help me out.
This is the program which i have bolded.
{You will write a Java class to play the TicTacToe game. This program will have at least two data members, one for the status of the board and one to keep track of whose turn it is. All data members must be private. You will create a user interface that allows client code to play the game.
The user interface must include:
� Boolean xPlay(int num) which allows x to play in the square labeled by num. This function will return true if that play caused the game to end and false otherwise.
� Boolean oPlay(int num) which allows o to play in the square labeled by num. This function will return true if that play caused the game to end and false otherwise.
� Boolean isEmpty(int num) will check to see if the square labeled by num is empty.
� Void display() which displays the current game status to the screen.
� Char whoWon() which will return X, O, or C depending on the outcome of the game.
� You must not allow the same player to play twice in a row. Should the client code attempt to, xPlay or oPlay should print an error and do nothing else.
� Also calling whoWon when the game is not over should produce an error message and return a character other than X, O, or C.
� Client code for the moment is up to you. Assume you have two human players that can enter the number of the square in which they want to play.
Verifying user input WILL be done by the client code.}Hi,

Help with structure of TICTacToe grid
hi, I'm trying to get the tictactoe grid to print out...
123
456
789
but it keeps missing '1' in the grid output i.e.....
23
456
789
Please can anyone point out where I've gone wrong.
here is my code for the grid.....
String s = "0123456789";
public void printBoard(String s)
int i = 1;
while(i < s.length())
i++;
int pos = i%3;
if( pos !=0)
myPrint(Character.toString((s.charAt(i))));
else
myPrintln(Character.toString((s.charAt(i))));
myPrintln("");
Many thanks
DaveSorry, you had multiple errors. Try this (where I used System.out to print the data):
public static void printBoard(String s) {
int i = 0;
while (i < s.length()-1) {
i++;
int pos = i % 3;
if (pos != 0) {
System.out.print(Character.toString( (s.charAt(i))));
else {
System.out.println(Character.toString( (s.charAt(i))));
System.out.println("");

I need help with my Tictactoe. can't switch between players Please Please
You will be building a Tic Tac Toe program, I have provided a program shell that has four functions:
printBoard- Prints the board as shows in the comments at the top of the file.
hasWon - Takes in a player's marker and tells us if that player has won
markTheBoard - marks the given location with the player's marker
isTie - Tells if there are no more spots and no winner
The play starts with X, the variable turn will keep track of who's turn it is.
At the beginning you will display the board with position numbers so the player knows how to place his/her marker.
The code will ask each player where they would like to place their marker until either
there are no more spots to play or one of the players wins.
The shell program is here

Can you help me with mouse pressed method please?
hi
can you help me with my problem please, player label doesn't show up in the applet and the draw string method it doesn't draw any strings like X or O for the game I don't know what is the problem maybe it is with MousePressed method which is in Board class. I tried to write the code of the location many times I'm not sure if the problem comes from there.
there is no error in my code, but it doesn't work.
this is class Board which has the mouseListener

Edited by: mshadows on May 18, 2008 7:53 AMI was playing with this a little bit and came up with this game model, something that I'm sure can be improved upon greatly:

HELP!!!This isn't a code writing service.
Start your own thread, rather than reviving one that is very old. And ask a question: that is, actually describe in what respect your program is not working. Often the most effective way of doing this is to post some code whose runtime behaviour is not what you expect or intend. If you do post code make sure it's brief and to the point (ie just illustrates the problem you are having). To make sure your code is readable when you post it here use the code tags: put {code} at the start of your code and the same thing again at the end. -
Hi,
I'm taking an introductory Java class, and I'm just trying to complete an assignment in my textbook. Here is a copy of the code that I'm having a problem with:
import java.util.Scanner;
public class TicTacToeClient
public static void main( String [] args )
Scanner scan = new Scanner( System.in );
TicTacToe ttt1 = new TicTacToe( );
String garbage;
int player = 1;
boolean gameOver = false;
int position;
while ( ! gameOver )
System.out.print( "Please enter a position, player " + player + " > " );
while( ! scan.hasNextInt( ) )
garbage = scan.nextLine( );
System.out.print( "Please enter a valid position, player " + player + " > " );
position = scan.nextInt( );
if ( ! ttt1.isLegal( position ) )
System.out.println( "This position is already used!" );
else
ttt1.makeMove( player, position );
if ( ttt1.gameWon( player ) || ttt1.isTie( ) )
gameOver = true;
else
if ( player == 1 )
player = 2;
else
player = 1;
ttt1.printWinner( player );
I'm very sorry if the format of this code is hard to read, as the message textbox is pretty small.
Anyhow, when I enter 0 for player 1, and then an invalid character for player 2 ( such as 'j' ), I get the "Please enter a valid value ..." message twice in a row. I thought that the scan.hasNextInt( ) condition in the while loop would wait for the user to press Enter before repeating the loop. Why does this happen and how can I correct it?
Thanks in advance for your help.

invinciBillThanks for the link.
This should be easier to read:
import java.util.Scanner;
public class TicTacToeClient
public static void main( String [] args )
Scanner scan = new Scanner( System.in );
TicTacToe ttt1 = new TicTacToe( );
String garbage;
int player = 1;
boolean gameOver = false;
int position;
while ( ! gameOver )
System.out.print( "Please enter a position, player " + player + " > " );
while( ! scan.hasNextInt( ) )
garbage = scan.nextLine( );
System.out.print( "Please enter a valid position, player " + player + " > " );
position = scan.nextInt( );
if ( ! ttt1.isLegal( position ) )
System.out.println( "This position is already used!" );
else
ttt1.makeMove( player, position );
if ( ttt1.gameWon( player ) || ttt1.isTie( ) )
gameOver = true;
else
if ( player == 1 )
player = 2;
else
player = 1;
ttt1.printWinner( player );

I am very new to java and our teacher has given us a program
that i am having quite a bit of trouble with. I was wondering if anyone could help me out.
This is the program which i have bolded.
{You will write a Java class to play the TicTacToe game. This program will have at least two data members, one for the status of the board and one to keep track of whose turn it is. All data members must be private. You will create a user interface that allows client code to play the game.
The user interface must include:
� Boolean xPlay(int num) which allows x to play in the square labeled by num. This function will return true if that play caused the game to end and false otherwise.
� Boolean oPlay(int num) which allows o to play in the square labeled by num. This function will return true if that play caused the game to end and false otherwise.
� Boolean isEmpty(int num) will check to see if the square labeled by num is empty.
� Void display() which displays the current game status to the screen.
� Char whoWon() which will return X, O, or C depending on the outcome of the game.
� You must not allow the same player to play twice in a row. Should the client code attempt to, xPlay or oPlay should print an error and do nothing else.
� Also calling whoWon when the game is not over should produce an error message and return a character other than X, O, or C.
� Client code for the moment is up to you. Assume you have two human players that can enter the number of the square in which they want to play.
Verifying user input WILL be done by the client code.}This is the program which i have bolded.Hmmm, that doesn't look like any programming language I've ever seen. I guess you have the wrong forum here, because it isn't Java.
That looks like a natural-language programming language that directly understands a homework assignment. Either that, or you really did just post the assignment. You wouldn't have done that though, right? -
Hello Sir/Mam,
Im Sanjeev Das from Bhilai(C.G.). Doing my B.E.(C.S.) and in final year from RCET, Bhilai.And has been selected by RISPL, Bhilai and Lambent, Nagpur mobiles companies.
My J2ME training was completed from RISPL on June of calendar year. RISPL is the Bhilai`s only InfoTech company that works on J2ME and Brew Tech.
Now with my hand I have three Game :-
1. Chakravue....(The Maze).
2. Tic-Tac-Toe.
3. Brick Game.
Now Im interested in application program that�s why my next project is �MobileBluetoothApplication� in which Im providing user to exchange data like image, text, sound�etc files through Bluetooth.
But one problem is there. Im not able to send the text and sound files through the Bluetooth. Please help me so that my project can grow up and perform the best result.Hi !
Place this code net benas file or any editor
it will work on stand alone phone

Does anyone notice any errors that i might have over looked?
thanksOk scratch out that entire code, i started over and it still won't compile.
import java.awt.*;
import javax.swing.*;

public class TicTacToe implements ActionListener{
private int[][] winCombinations = new int[][]{
{1, 2, 3}, {4, 5, 6}, {7, 8, 9},

{1, 5, 9}, {3, 5, 7}
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 class PressedButton{
public void actionPerformed(ActionEvent a) {
count++;
if(count % 2 == 0){
letter = "O";
} else {
letter = "X";
for(int t=1; t<=9; t++){
if(a.getSource() == buttons[t]){
buttons[t].setText(letter);
buttons[t].setEnabled(false);
for(int i=0; i<=7; i++){
if( buttons[winCombinations[t][0]].getText() == buttons[winCombinations[t][1]].getText() &&
buttons[winCombinations[t][1]].getText() == buttons[winCombinations[t][2]].getText() &&
buttons[winCombinations[t][0]].getText() != ""){
win = true;
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 a tie!");
System.exit(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? -

get this working I will give them dukes!!!!!
your manifest file should look like this...
Manifest-Version: 1.0
Main-Class: tictactoeplease note there must be a line return at the end of tictactoe. so the file should have three lines.
if you have this correct the only other thing i can suggest is are you sure it is your manifest file that is being added to the jar.
your jar command should look like the following assuming the jar files is called Game, your manifest is called game.mf and both files reside in the default package.
jar -cvfm Game.jar game.mf *.class hope this helps.
