Reviews

"Kursova on Java is a library management system with Factory, Observer, Strategy patterns. UML in StarUML. The code is structured, SOLID is observed!"

"The OOP course in C# is a "naval battle" game with State, Command patterns. WPF interface, class diagrams. Protected perfectly!"

VNTU, Vinnytsia

"Python OOP — online store with Singleton (DB), Factory (goods), Observer (notifications) patterns. Clean code, pytest tests."

Frequently asked questions

Java is an OOP classic with strict typing. C# is the equivalent of Java for .NET. Python — simpler syntax, duck typing. C++ is the most complex, but powerful. The choice depends on the course requirements.

Yes, we create all types of UML diagrams: class diagram, sequence, state, activity, component, deployment. We use StarUML, PlantUML or draw.io.

All 23 GoF patterns: Creational (Singleton, Factory, Builder, Prototype, Abstract Factory), Structural (Adapter, Bridge, Composite, Decorator, Facade, Flyweight, Proxy), Behavioral (Observer, Strategy, Command, State, Template, Iterator, etc.).

Yes, for each SOLID principle we provide: a definition, an example of violation, an example of compliance in your code. We show how refactoring improves the architecture.
