Answer from AI
SOLID is a set of five principles of object-oriented programming that help create flexible, extendable, and maintainable code:
-
S — Single Responsibility Principle: a class should have only one reason to change, meaning it should perform only one task.
-
O — Open/Closed Principle: software entities should be open for extension but closed for modification.
-
L — Liskov Substitution Principle: objects of subclasses should be interchangeable with objects of the base class without affecting the correctness of the program.
-
I — Interface Segregation Principle: clients should not depend on interfaces they do not use.
-
D — Dependency Inversion Principle: high-level modules should not depend on low-level modules; both should depend on abstractions.
These principles help write code that is easier to test, maintain, and extend.
