🎮 Tic Tac Toe

We developed a terminal-based version of the classic game Tic Tac Toe. This is a backend project in Java 21 built collaboratively using agile methodologies.

📌 Project Objectives

Implement the core logic of the Tic Tac Toe game in a terminal interface, following the game’s rules:

• Two players: X and O
• Player X starts the game
• Played on a 3x3 grid
• A player wins by aligning three matching symbols in a row, column, or diagonal
• If all cells are filled without a winner, it’s a draw
• The board is displayed after each turn
• At the end, a message is shown indicating the winner or a draw

🧠 Technical Skills

• Backend development in Java
• Object-Oriented Programming (OOP)
• Control flow (conditionals and loops)
• Multidimensional array handling
• User input via Scanner

💻 Technologies Used

• Java 21

🛠 Tools

• IntelliJ IDEA
• Git & GitHub (with GitFlow)
• Trello (for agile project management)
• Figma (for flow chart design)
  
• Google Meet, Zoom, Whatsapp (communication channels)

📋 Functional Requirements

• Display the empty board at the start
• Show the current board after each move
• Allow moves via row and column input
• Validate if the selected cell is already occupied
• Check for a winner after each move
• Detect draw when all cells are filled without a winner
• Show a message declaring the winner or a draw
• Follow GitFlow workflow
  

📓 Non-Functional Requirements

• Terminal-based (console) user interface
• Follows Java best practices and conventions
• Clean, readable, and well-named code (classes, methods, variables)
