  🌟 SOLID Principles SOLID is a set of five object-oriented design principles that help you write clean, maintainable, and flexible code. S – Single Responsibility Principle (SRP) One class = One responsibility ✔ A class should do only one job ✔ It should have only one reason to change Example: A Book class should only store book data. Validation should be in another class. O – Open/Closed Principle (OCP) Open for extension, closed for modification ✔ You should be able to add new features ✔ Without changing existing code Example: Instead of modifying a class, create a subclass to extend behavior. L – Liskov Substitution Principle (LSP) Child classes should behave like parent classes ✔ A subclass should be usable wherever the parent class is used ✔ It should not break the program Example: A Square should behave like a Rectangle if it extends Rectangle. I – Interface Segregation Principle (ISP) No class should be forced to implement methods it doesn’t us...
