Checkers is a playable Java board game developed as a three-person university project during the Summer Semester 2025.

The project focuses on object-oriented design, graphical user interface development, game-state handling, and collaborative implementation.

• Playable checkers game with a graphical user interface
• Separation into model/, view/, and controller/
• Standard game mode with the regular starting position
• Debug mode for preparing and testing custom board situations
• UML documentation of the project structure

The corresponding UML source file is available in dame.uml.

Java 17 or newer is recommended.

Check the installed versions with:

java -version
javac -version

The project does not use a dedicated build system and can be compiled directly with javac.

javac Main.java controller/*.java view/*.java model/*.java
java -cp ".;view;controller;model" Main

javac Main.java controller/*.java view/*.java model/*.java
java -cp ".:view:controller:model" Main

The additional classpath entries are required because the classes are stored in subdirectories without Java package declarations.

Starts a regular match using the standard checkers starting position.

Starts with an empty board so that specific game situations can be prepared and tested manually.

This repository contains the completed result of a university team project.

The project demonstrates:

• object-oriented Java development
• GUI implementation
• separation of responsibilities
• board-game rule handling
• collaborative development in a three-person team

• Introduce Java package declarations
• Add Maven or Gradle as a build system
• Add automated tests for move validation and game rules
• Improve the separation between game logic and the user interface
• Add save and load functionality
• Add move history or replay support
