Answer from AI
The SOLID principles are a set of five fundamental object-oriented design rules that help create flexible, extendable, and maintainable programs:
-
S (Single Responsibility Principle) — The principle of single responsibility: a class should have only one reason to change, meaning it should be responsible for a single task.
-
O (Open/Closed Principle) — The principle of open/closed: software entities should be open for extension but closed for modification.
-
L (Liskov Substitution Principle) — The Liskov Substitution Principle: objects of subclasses should be interchangeable with objects of the superclass without affecting the correctness of the program.
-
I (Interface Segregation Principle) — The interface segregation principle: clients should not depend on interfaces they do not use.
-
D (Dependency Inversion Principle) — The dependency inversion principle: high-level modules should not depend on low-level modules; both should depend on abstractions.
These principles help reduce code coupling, increase reusability, and simplify maintenance.
