Question
I need in java.Code an interactive, two-player game of Tic-Tac-Toe that has a graphical user interface. You should implement also a decent AI module (you play against the computer and the computer should not play randomly). I provide a little more details in the following: The idea is to play the game Tic-Tac-Toe (which is a two player game) with the computer. Thus there will be one player in front of the computer and the second player will be played by the computer (AI, that is why I specified that the computer should not play randomly). I hope this clarifies the requirements, I need new code in java because what are in chegg those getting errors and explain clearly with screen shots.
Explanation / Answer
Please find my implementation:
import java.util.Arrays;
import java.util.InputMismatchException;
import java.util.Scanner;
public class TicTacToe {
static Scanner in;
static String[] board;
static String turn;
public static void main(String[] args) {
in = new Scanner(System.in);
board = new String[9];
turn = "X";
String winner = null;
populateEmptyBoard();
System.out.println("Welcome to 2 Player Tic Tac Toe.");
System.out.println("--------------------------------");
printBoard();
System.out.println("X's will play first. Enter a slot number to place X in:");
while (winner == null) {
int numInput;
try {
numInput = in.nextInt();
if (!(numInput > 0 && numInput <= 9)) {
System.out.println("Invalid input; re-enter slot number:");
continue;
}
} catch (InputMismatchException e) {
System.out.println("Invalid input; re-enter slot number:");
continue;
}
if (board[numInput-1].equals(String.valueOf(numInput))) {
board[numInput-1] = turn;
if (turn.equals("X")) {
turn = "O";
} else {
turn = "X";
}
printBoard();
winner = checkWinner();
} else {
System.out.println("Slot already taken; re-enter slot number:");
continue;
}
}
if (winner.equalsIgnoreCase("draw")) {
System.out.println("It's a draw! Thanks for playing.");
} else {
System.out.println("Congratulations! " + winner + "'s have won! Thanks for playing.");
}
}
static String checkWinner() {
for (int a = 0; a < 8; a++) {
String line = null;
switch (a) {
case 0:
line = board[0] + board[1] + board[2];
break;
case 1:
line = board[3] + board[4] + board[5];
break;
case 2:
line = board[6] + board[7] + board[8];
break;
case 3:
line = board[0] + board[3] + board[6];
break;
case 4:
line = board[1] + board[4] + board[7];
break;
case 5:
line = board[2] + board[5] + board[8];
break;
case 6:
line = board[0] + board[4] + board[8];
break;
case 7:
line = board[2] + board[4] + board[6];
break;
}
if (line.equals("XXX")) {
return "X";
} else if (line.equals("OOO")) {
return "O";
}
}
for (int a = 0; a < 9; a++) {
if (Arrays.asList(board).contains(String.valueOf(a+1))) {
break;
}
else if (a == 8) return "draw";
}
System.out.println(turn + "'s turn; enter a slot number to place " + turn + " in:");
return null;
}
static void printBoard() {
System.out.println("/---|---|---\");
System.out.println("| " + board[0] + " | " + board[1] + " | " + board[2] + " |");
System.out.println("|-----------|");
System.out.println("| " + board[3] + " | " + board[4] + " | " + board[5] + " |");
System.out.println("|-----------|");
System.out.println("| " + board[6] + " | " + board[7] + " | " + board[8] + " |");
