Assignment 2 - TicTacToe

Learning objectives

You will practice using reference variables, arrays, and performing operations on arrays.

Problem

Your friend wants to implement a Tic-Tac-Toe game in Java. They have already started but got stuck and now ask you for your help to finish it.

Your task

Your task is to implement the Tic-Tac-Toe game.

You can find and download the code template here. The game should allow two players to take turns and make moves on a 3x3 game board. The program checks for a win, loss, or draw after each move.

The Game

Game Requirements

There are TODOs in the code. Make sure to follow them.

• GameBoard represents the Tic-Tac-Toe game board.
  • Use a 2D array to represent the cells on the board
  • Each cell can be empty, contain an X, or contain an O
  • Hint: An empty cell could be stored as a -, does not need to be printed.
• • Player represents a player in the game.
  • Store the player's name and symbol (X or O)
• Game Logic: The main game logic should be inside the TicTacToe class (make use of methods!).
  • Implement promptPlayerMove() that asks players to make a move on the game board.
  • Implement the game logic, consider the following:
    • Check if the board is full
    • Check for a win condition
    • Take a player's move and update the board
    • Switch between players after each move
• User Interaction:
  • After each move, the current board should be printed to the console in a nice, readable format, containing each player's placed symbols
  • Prompt the user to place a move; the input should be used to make a move
  • When the game ends (the board is full), display a message to announce the winner or declare a draw
  • Ask if the players want to play again after each game (yes/no). If a player wants to play again, restart the game automatically
• Input Validation: Make sure that all user input is valid and does not cause the game to unexpectedly abort!

Other considerations

• Please make sure to provide expressive comments, print statements, and variable names.
• Make sure to follow object-oriented principles and Java best practices!
• Explanation of the game: https://en.wikipedia.org/wiki/Tic-tac-toe
• If you type 'tic tac toe' in Google, you can play it :-)

Bonus challenges (optional)

• Provide a more user-friendly and more sophisticated way of requesting user input to map to the game board (instead of 00, 01, 02, 10, 11, 12, 20, 21, 22)
• Feel free to add your own (more complex) customization to the project!

Happy coding!
