These principles were introduced by Robert C. Martin, also known as Uncle Bob. They are: Single Responsibility Principle (SRP) Open/Closed Principle (OCP) Liskov Substitution Principle (LSP) Interface Segregation Principle (ISP) Dependency Inversion Principle (DIP) 1. Single Responsibility Principle (SRP) A class should have only one reason to change, meaning it should have only one job or responsibility. Importance: Promotes cohesive functionality. Simplifies debugging and testing. Makes the system more understandable and reduces the risk of changes affecting unrelated functionalities. 2. Open/Closed Principle (OCP) Software entities (classes, modules, functions, etc.) should be open for extension but closed for modification. Importance: Encourages code reuse and flexibility. Reduces the risk of introducing b...
