Question

Write a program that allows two players to play a game of tic-tac-toe. Use a two-dimensional 3x3 char array to represent the game board. Each element of the array should be initialized with an asterisk. The program should utilize a loop to do the following:

NOTE: You can assume that I will only use correct inputs (no indexs that are above or below the correct values). You can also assume that a player cannot make the same move twice, or place an X or O in the same spot as another player. You may write your code to prevent this, but if you don't I won't take off points for it.

Explanation / Answer

import java.util.Scanner; /** * Tic-Tac-Toe: Two-player console, non-graphics, non-OO version. * All variables/methods are declared as static (belong to the class) * in the non-OO version. */ public class TTTConsoleNonOO2P { // Name-constants to represent the seeds and cell contents public static final int EMPTY = 0; public static final int CROSS = 1; public static final int NOUGHT = 2; // Name-constants to represent the various states of the game public static final int PLAYING = 0; public static final int DRAW = 1; public static final int CROSS_WON = 2; public static final int NOUGHT_WON = 3; // The game board and the game status public static final int ROWS = 3, COLS = 3; // number of rows and columns public static int[][] board = new int[ROWS][COLS]; // game board in 2D array // containing (EMPTY, CROSS, NOUGHT) public static int currentState; // the current state of the game // (PLAYING, DRAW, CROSS_WON, NOUGHT_WON) public static int currentPlayer; // the current player (CROSS or NOUGHT) public static int currntRow, currentCol; // current seed's row and column public static Scanner in = new Scanner(System.in); // the input Scanner /** The entry main method (the program starts here) */ public static void main(String[] args) { // Initialize the game-board and current status initGame(); // Play the game once do { playerMove(currentPlayer); // update currentRow and currentCol updateGame(currentPlayer, currntRow, currentCol); // update currentState printBoard(); // Print message if game-over if (currentState == CROSS_WON) { System.out.println("'X' won! Bye!"); } else if (currentState == NOUGHT_WON) { System.out.println("'O' won! Bye!"); } else if (currentState == DRAW) { System.out.println("It's a Draw! Bye!"); } // Switch player currentPlayer = (currentPlayer == CROSS) ? NOUGHT : CROSS; } while (currentState == PLAYING); // repeat if not game-over } /** Initialize the game-board contents and the current states */ public static void initGame() { for (int row = 0; row
