The Minesweeper video game in Java

Minesweeper

Sample Java application with JavaFX. Demonstration application used in the book Introduction to Software Design with Java.

The goal of this project is to help illustrate various design decisions related to abstraction, encapsulation, and information hiding, in the context of a complete working application. The rest of the code has been left to a minimum. Common best practices not implemented here would include externalizing strings and using icons in the UI.

This application was also designed to be simple enough to be realizable without the help of the Observer pattern. Although using the Observer as part of this design would make a sense, the idea here was to have a code base that could be used for discussion without knowing about the Observer pattern.

Building this application

This repository is configured to build automatically in Eclipse with Java 21 and JavaFX 21.

However, when first imported, the project will show a compilation error because the JavaFX dependency is missing.

To add JavaFX:

1. Download JavaFX 21;
2. Create a new User Library under Eclipse -> Window -> Preferences -> Java -> Build Path -> User Libraries -> New. Name it JavaFX21 and include the jars under the lib folder from the location where you extracted the JavaFX download.

The project should then build properly.
