Dominik Przybysz

Stop treating classes as mere data structures. Rediscover core OOP principles to escape fragile framework conventions and build truly decoupled, maintainable software.

#1 about 4 min

Core definitions and principles of object-oriented programming

Modeling programs as communicating objects relies on foundational structural design principles.

#2 about 9 min

Encapsulation strategies for avoiding anemic domain models

Replacing default getters and setters with domain-specific operations secures internal state.

#3 about 8 min

Abstraction and delegating logic through information experts

Hiding implementation details and assigning logic to data-holding objects reduces system complexity.

#4 about 5 min

Managing single responsibilities with cohesion and coupling metrics

Measuring lack of cohesion helps split classes while visual exercises aid in minimizing module coupling.

#5 about 7 min

Dependency inversion for clean architectural boundaries and abstractions

Relying on stable interfaces rather than concrete classes prevents leaky abstractions in domain logic.

#6 about 11 min

Inheritance constraints and prioritizing composition over inheritance

Respecting substitution contracts and open-closed principles prevents rigid class hierarchies and unintended coupling.

#7 about 4 min

Leveraging polymorphism for robust application programming interfaces

Using method overriding and overloading enables flexible and gracefully evolving software contracts.

#8 about 6 min

Key takeaways and developer reflections on language choices

Deliberate software design choices matter more than blindly applying convenient language features.
