Understanding the SOLID Principles in Object-Oriented Programming
Writing clean, maintainable code isn't just about making it work — it's about making it easy to change, extend, and debug . That’s exactly what the SOLID principles aim to help developers achieve. If you’ve ever struggled with messy, fragile codebases, mastering these five principles will change the way you write software. Let's explore each SOLID principle and see how it improves object-oriented programming (OOP). What Does SOLID Stand For? SOLID is an acronym for five design principles that make software designs more understandable, flexible, and maintainable: S – Single Responsibility Principle O – Open/Closed Principle L – Liskov Substitution Principle I – Interface Segregation Principle D – Dependency Inversion Principle Each of these principles addresses a different aspect of software design. Together, they form the foundation of good object-oriented architecture. 1. Single Responsibility Principle (SRP) Definition : A class should ha...
