What are SOLID Principles?
The SOLID acronym stands for:
- S — Single Responsibility Principle (SRP)
- O — Open/Closed Principle (OCP)
- L — Liskov Substitution Principle (LSP)
- I — Interface Segregation Principle (ISP)
- D — Dependency Inversion Principle (DIP)
These five principles were introduced by Robert C. Martin (Uncle Bob) and have become the foundation of Object-Oriented Design (OOD).
