Explain the SOLID principles used in your project.

Question

Accepted Answer

SOLID principles are five design principles aimed at making software designs more understandable, flexible, and maintainable.

S - Single Responsibility Principle: A class should have one reason to change. Example: A User class should only handle user data, not user authentication.
O - Open/Closed Principle: Software entities should be open for extension but closed for modification. Example: Using interfaces to add new functionalities without changing existing code.
L - Liskov Substitution Principle: Subtypes must be substitutable for their base types. Example: If a Bird class has a method fly(), then a Penguin subclass should not inherit from it.
I - Interface Segregation Principle: Clients should not be forced to depend on interfaces they do not use. Example: Instead of one large interface, create smaller, specific ones.
D - Dependency Inversion Principle: High-level modules should not depend on low-level modules. Both should depend on abstractions. Example: Using dependency injection to manage dependencies.

Accepted Answer

SOLID stands from acronym:
* Single responsibility - class should have only one responsibility
* Open closed - class should be open for extension but closed to modification
* Liskov substitution - subclasses should be able to replace main class occurance without breaking existing behaviour
* Interface segregation - using smaller interfaces is better than one big one
* Dependency Inversion - classes should rely on abstraction instead of concrete implementation
