Tic-Tac-Toe Java Project

Project Description

This project is a Java console-based Tic-Tac-Toe application that includes both a standard 2D Tic-Tac-Toe game and an extended 3D Tic-Tac-Toe version.

The 2D version uses a 3 by 3 board, while the 3D version uses a 4 by 4 by 4 board. Both versions allow two human players to take turns, place their symbols on empty cells, check for winning conditions, and detect draw situations.

The project demonstrates object-oriented programming concepts in Java, including classes, enums, arrays, methods, encapsulation, game logic, and console input handling.

Technologies Used

• Java
• Object-Oriented Programming
• Java Arrays
• Java Enum
• Java Scanner
• Console-Based Application

Features

• Standard 2D Tic-Tac-Toe game
• 3D Tic-Tac-Toe game on a 4 by 4 by 4 board
• Two-player turn-based gameplay
• Board initialization with empty cells
• Move validation
• Win detection
• Draw detection
• Console-based board display
• Separate game logic and main execution files
• Enum-based cell representation using X, O, and EMPTY

2D Tic-Tac-Toe

The 2D version uses a 3 by 3 board. Two players take turns entering row and column values. Player 1 uses X, and Player 2 uses O.

The game checks the following winning conditions:

• Rows
• Columns
• Diagonals

If all cells are filled and no player wins, the game ends as a draw.

3D Tic-Tac-Toe

The 3D version uses a 4 by 4 by 4 board. Two players take turns entering level, row, and column values.

The game checks the following winning conditions:

• Rows within each level
• Columns within each level
• Vertical connections across levels
• Diagonals within levels
• Diagonals across levels

The 3D version extends the standard Tic-Tac-Toe logic by using a three-dimensional array.

How to Compile and Run

Because both versions contain a Main.java file, compile and run each version separately.

Running the 2D Version

Compile

javac 2d-tic-tac-toe/TicTacToe.java 2d-tic-tac-toe/Main.java

Run

java -cp 2d-tic-tac-toe Main

Running the 3D Version

Compile

javac 3d-tic-tac-toe/TicTacToe3D.java 3d-tic-tac-toe/Main.java

Run

java -cp 3d-tic-tac-toe Main

Example 2D Gameplay

- - -
Player 1's turn. Enter row and column (1-3):

The player enters a row and column number between 1 and 3.

Example 3D Gameplay

Level 1:

Level 2:

Player 1's turn. Enter level (1-4), row (1-4), and column (1-4):

The player enters a level, row, and column number between 1 and 4.

Notes

• The project uses console input and output.
• The 2D and 3D versions are stored in separate folders because both versions use a Main.java file.
• Invalid moves are rejected if the selected position is outside the board or already occupied.
• The program continues until one player wins or the game ends in a draw.
• No external libraries are required.

Purpose of the Project

The purpose of this project is to practice Java object-oriented programming through a simple game-based application. It focuses on using classes, enums, arrays, methods, condition checking, and user input in Java.

Project Outcome

This project demonstrates the ability to design and implement turn-based game logic in Java. It also shows how standard 2D game logic can be extended into a 3D version using multidimensional arrays.
