I'm working on a Tic Tac Toe game with java and need to implement it with the MVC pattern. Just wondering on what will be a good place to start? I have a working game currently only using java.

//Tic-Tac-Toe. Two player.

//Feel free to use as a starting point for 5x5 and separating into MVC.

import java.util.Scanner;



public class TicTacToe {

   static final int X = 1;

   static final int O = -1;



   //printBoard method that prints out the current state of the

   //Tic-Tac-Toe board. Does not return anything or change the board.

   public static void printBoard( int  matrix ){



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

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

            // Uses the "global" constants to print out appropriate letter.

            if( matrix[row][col] == X )

               System.out.print("X ");

            else if(matrix[row][col] == O )

               System.out.print("O ");

            else 

               System.out.print(". ");

          }

          // Goes to new line after printing each row

          System.out.println("");

       }

   }



   //hasWon returns true if there was a win or a cat game.

   public static boolean hasWon( int  matrix ){

      //Variable holds the "result" of hasWon. True if a winner was found.

      boolean retVal = false;



      //Check for horizontal win

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

         int sum = 0;

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

            sum += matrix[row][col];

         }

         //Check to see if the sum of that row was 3 or -3, a win...

         if( sum == 5 ){

            System.out.println("X wins.");

            retVal = true;

         } else if ( sum == -5 ) {
