Java Object-Oriented Programming Portfolio

Curated collection of Java object-oriented programming case studies developed from academic coursework and exam-style exercises.

The repository groups multiple independent Java/Maven projects focused on domain modeling, collections, maps, exception handling, data aggregation, statistics, GUI interaction, and test-driven implementation.

This is a cleaned portfolio version: duplicated folders, incomplete intermediate versions, nested Git repositories, build artefacts, compiled classes, IDE metadata and original CI files have been removed.

Build and test

Each project is independent.

From a project folder:

mvn clean test

Example:

cd oop-tv-series-database
mvn clean test

To test all projects locally, run the commands listed in TESTING.md.

Continuous integration

The repository includes a GitHub Actions workflow that runs Maven tests on all included projects using Java 17.

Publication note

This repository is intended as a professional portfolio version of academic Java/OOP exercises.

• nested .git folders;
• Maven target/ folders;
• compiled .class files;
• IDE metadata such as .project, .classpath, .settings;
• GitLab CI files from the original coursework environment;
