Tic tac toe problem please help

Question

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
Dave

this 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)
import java.io.*;
class TicTacToeConsole
  BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
  String[] board = new String[9];
  public TicTacToeConsole()
    for(int x = 0; x < board.length; x++) board[x] = " _ ";
    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");
  public void printAvailableSquares()
    System.out.println();
    for(int x = 0; x < board.length; x++)
      if(board[x].equals(" _ ")) System.out.print(" " + (x+1) + " ");
      else System.out.print("   ");
      if(x%3 == 2) System.out.println("\n");
  public static void main(String[] args){new TicTacToeConsole();}
}
