Tic Tac Toe Java

Hello and good afternoon I am having some problems trying to follow the instructions for this assignment.

Fo far this is my code with the instruccions

import java.util.Random; import java.util.Scanner; public class TicTacToe { public static void main ( String[] args ) { Scanner in = new Scanner ( System.in ); char[][] board = new char[ 3 ][ 3 ];

// Initialize the board to spaces for (int row=0; row

// Keep playing while the game isn't finished

// Get the location from the user and validate it

// Mark the position in the board according to the user's specified location

// Print the board after the user plays

// Check to see if the game is finished. If it is, break out of the loop.

// Have the AI make a move

// Print the board after the AI plays

// Check to see who the winner is

// If the winner is 'X' or 'O', print that, otherwise, it is a tie }

/** * Makes a move for the AI, and marks the board with an 'O'. * * @param board The game board */ public static void moveAI ( char[][] board ) { // Validate that the random location generated is valid. // Keep recalculating the location if the one generated is not // an empty space.

// Be sure to mark the position in the board with an 'O' }

/** * Prints out the tic-tac-toe board * * @param board The game board */ public static void printBoard ( char[][] board ) { // Box drawing unicode characters:

char a = '\u250c'; // U+250C : top-left char b = '\u2510'; // U+2510 : top-right char c = '\u2514'; // U+2514 : bottom-left char d = '\u2518'; // U+2518 : bottom-right char e = '\u252c'; // U+252C : top-vertical-connector char f = '\u2534'; // U+2534 : bottom-vertical-connector char g = '\u251c'; // U+251C : left-horizontal-connector char h = '\u2524'; // U+2524 : right-horizontal-connector char i = '\u253c'; // U+253C : center plus sign connector char j = '\u2500'; // U+2500 : horizontal char k = '\u2502'; // U+2502 : vertical String l = j + "" + j + "" + j; // Three horizontals

// Print out the game board

System.out.printf ( " 0 1 2 " + " %c%s%c%s%c%s%c " + "0 %c %c %c %c %c %c %c " + " %c%s%c%s%c%s%c " + "1 %c %c %c %c %c %c %c " + " %c%s%c%s%c%s%c " + "2 %c %c %c %c %c %c %c " + " %c%s%c%s%c%s%c ", a, l, e, l, e, l, b, k, board[0][0], k, board[0][1], k, board[0][2], k, g, l, i, l, i, l, h, k, board[1][0], k, board[1][1], k, board[1][2], k, g, l, i, l, i, l, h, k, board[2][0], k, board[2][1], k, board[2][2], k, c, l, f, l, f, l, d );
