I'm in need helping implement Code Tictactoe Java. I have three classes need to implement . The last picture is the output Thank you so

The Model class . Prefer the pictures for all the explanation code Thanks

The View class

Class Controller
public class TicTacToeController {

public void start() { /* MAIN LOOP (repeats until game is over) */
// INSERT YOUR CODE HERE /* Display Results and Exit */
view.showBoard(model.toString());

Square class :
public enum TicTacToeSquare { /*X*/ X("X"), /* O*/ O("O"), /* Empty Square*/ EMPTY(" "); private String message; private TicTacToeSquare(String msg) { message = msg; } @Override public String toString() { return message; } }
The State Class :
public enum TicTacToeState { /* The game is over, and X is the winner */ X("X"), /* The game is over, and O is the winner */ O("O"), /*The game has ended in a tie (no winner)*/ TIE("TIE"), /*The game is still in progress (no winner)*/ NONE("NONE"); private String message; private TicTacToeState(String msg) { message = msg; } @Override public String toString() { return message; } }
Output picture
