Trying to add an ai part to my code but dont know where to start or how would I do this with the code I have created to have 1v1 player vs player but i want to add the player vs ai part!

MAIN CLASS

package tictactoe;

import java.util.Scanner;

/** * * @author */

public class TicTacToePractice {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

TicTacToe game = new TicTacToe();

System.out.println("TicTacToe");

do {

System.out.println("Board layout");

game.designboard();

int row;

int col;

do {

System.out.println("Player " + game.getPlayer() + " enter an empty row and column to place the x or o!");

row = scan.nextInt() - 1;

col = scan.nextInt() - 1;

} while (!game.placement(row, col));

game.changePlayer();

} while (!game.checkForWin() && !game.BoardFull());

if (game.BoardFull() && !game.checkForWin()) {

System.out.println("Draw");

} else {

System.out.println("current board layout:");

game.makeboard();

game.changePlayer();

System.out.println(Character.toUpperCase(game.getPlayer()) + "Wins!");

}
