IN JAVA: Modify the Tic-Tac-Toe coded game below to simulate playing a game. The basic flow for populating the board is:

For Player 1, pick a random space to move, if empty, place 1 in that space.

Now its Player 2 turn.

For Player 2, pick a random space to move, if empty place 2 in that space.

Now its Player 1 turn again.

Keep moving until the board is full or a player wins.

Then play 1000 iterations of the game, within 3 modes. After the thousand games in each mode, display the number of times X won, O won and ties. The three modes are: 1) X and O move randomly as described above. If a random square chosen has been played, have the player choose again. 2) X always moves to the middle square in the first move. 3) O always moves to the middle square in the first move, if X has not moved there.

Note: X always moves first

Your program should be structured like the following:

For mode from 1 to 3 {

For each game 1 to 1000 {

Play game considering the current mode

Add result to totals

}

Print totals (#Xwins, #Owins, #Ties)

}

X should win around 550 times in mode 1, 750 in mode 2 and 450 in mode. These are very approximate, as slight variations in your code can modify these slightly from other students.

HERE IS THE TIC TAC TOE CODED GAME (Copy and Paste):

import java.util.Random;

public class TwoDim {

public static void main(String[] args) {

int[][] board = new int[3][3];

Random r = new Random(12);

for (int row = 0; row < board.length; row++) {

for (int col = 0; col < board[row].length; col++) {

board[row][col]= r.nextInt(3);

}

}

PrintBoard(board);

boolean xwinner = CheckWin(1,board);

boolean owinner = CheckWin(2,board);

System.out.println(xwinner + "-" + owinner);

}

public static boolean CheckWin(int player ,int[][] inboard){

int PCNT;

for (int row = 0; row < inboard.length; row++) {

PCNT = 0;

for (int col = 0; col < inboard[row].length; col++) {

if (inboard[row][col]== player) { PCNT++;}

}

if (PCNT==3) {return true;}

}

return false;

}

public static void PrintBoard(int[][] inboard){

String letter="";

for (int row = 0; row < inboard.length; row++) {

for (int col = 0; col < inboard[row].length; col++) {

switch(inboard[row][col]) {

case 0: letter= " "; break;

case 1: letter= "X"; break;

case 2: letter= "O"; break;

}

System.out.print(letter + " ");

}

System.out.println("");

}

}

}
