Project Description

The Tic Tac Toe game application is a JavaFX project that utilizes the graphical user interface toolkit of Java. It is designed to create and display the traditional Tic Tac Toe game. The game features a snappy and straightforward user interface, presenting a 3×3 grid of buttons representing the playing board. The player can make movements by clicking the buttons. The game logic guarantees that proper moves are made, determines a winner, and manages the restart capability. The game also contains an AI opponent who makes intelligent plays and provides a tough gameplay experience by employing the Minimax algorithm with alpha-beta pruning. The GUI elements are built utilizing JavaFX’s layout containers and style tools to produce a pleasant visual presentation.

This project employs object-oriented programming principles, encapsulating the game logic within classes and methods to ensure modularity and reusable code. The event handling mechanism allows users to interact with the GUI and provides instant feedback through alerts and graphical updates. The game’s state is maintained through variables and arrays, while the AI player uses the Minimax algorithm to select the best move based on the current game state. Overall, this project demonstrates the use of JavaFX for building interactive graphical games and showcases the implementation of the classic Tic Tac Toe game with an AI opponent.

The final layout of the application should be as follows:
