Question

Pls I need this program .
It's my project.
Write a blue j program for tic tac Toe with using scanner and buffered reader and without using main class and private and public. Keep it as simple as possible.

Answer 1

So I have a basic code for running a tic-tac-toe board. I'm supposed to fill in the missing pieces, but I've having a lot of problems. I'm supposed to use double nested arrays I believe. 
Requirements: 
As soon as one player gets three in a row, the game should end.
If the board fills up, the program should print that there was a tie, and the game should end.
If the user enters a row/column that is outside the board (less than 0 or more than 2), print an error and let them enter another spot. Similarly, if they enter row/column and another piece is already in that spot, print and error and let them enter another position.

I mostly need some pointers, and any code help would be appreciated. When I've run the program, it just keeps looping through the Player X inputs and won't stop or show the board. What's in bold is what I have added to it.

JAVA CODE:
public class TicTacToe {

2 

3    private char[][] board;

4    private char currentPlayerMark;

5             

6    public TicTacToe() {

7        board = new char[3][3];

8        currentPlayerMark = 'x';

9        initializeBoard();

10    }

11     

12     

13    // Set/Reset the board back to all empty values.

14    public void initializeBoard() {

15         

16        // Loop through rows

17        for (int

40     

41     

42    // Loop through all cells of the board and if one is found to be empty (contains char '-') then return false.

43    // Otherwise the board is full.

44    public boolean isBoardFull() {

45        boolean isFull = true;

46         

47        for (int i = 0; i < 3; i++) {

48            for (int j = 0; j < 3; j++) {

49                if (board[i][j] == '-') {

50                    isFull = false;

51                }

52            }

53        }

54         

55        return

76     

77    // Loop through columns and see if any are winners.

78    private boolean checkColumnsForWin() {

79        for (int i = 0; i < 3; i++) {

80            if (checkRowCol(board[0][i], board[1][i], board[2][i]) == true) {

81                return true;

82            }

83        }

84        return false;

85    }

86     

87     

88    // Check the two diagonals to see if either is a win. Return true if either wins.

89    private boolean checkDiagonalsForWin() {

90        return ((checkRowCol(board, board

Answer 2

// Check minor diagonal lineFormed = true; for (int i = 1; i < board.length; i++) if (board[board.length - i][i - 1] != number || board[board.length - i - 1][i] != number) lineFormed = false; if (lineFormed) return true; return false; // If none of the lines is formed } }
