Question

The getMove method in TicTacToePlayer.java just places an ‘X’ or ‘O’ in a
random square. That square may even already be occupied. Change this method to intelligently play tic-tac-toe (for whatever piece it has been passed – X or O).


import java.util.Random;

public class TicTacToe {

public void getMove(char[][] theBoard, char myPiece) {

// this method should update the game board to place 'myPiece' (X or O)
// in a space on the board.

// As-is, this method just places an X or O randomly, without even considering
// if the square is already taken.

Random myRand = new Random();

int myRow = myRand.nextInt(3);
int myCol = myRand.nextInt(3);

theBoard[myRow][myCol] = myPiece;

}

}
