LLD Object-Oriented Design: Interfaces & Abstract Classes (Designing Contracts)
The article discusses the importance of interfaces and abstract classes in object-oriented design, particularly in system design. It emphasizes how these concepts help define clear behavioral contracts between components, promoting loose coupling and flexibility. By understanding the distinctions and applications of interfaces and abstract classes, developers can create more scalable and maintainable systems.
- ▪Interfaces define capability contracts that implementing classes must follow.
- ▪Abstract classes provide partial implementation along with abstract behavior contracts.
- ▪Using interfaces and abstract classes enhances system scalability and testability.
