SOLID- SOLID principles a quick dive through CODE

SOLID principles are the building blocks of good software design, emphasizing clarity, maintainability, and flexibility. Here's a quick dive into each:

1️⃣ Single Responsibility Principle (SRP): A class should have only one reason to change, meaning it should have only one responsibility or function.

2️⃣ Open/Closed Principle (OCP): Software entities should be open for extension but closed for modification. This encourages adding new features without altering existing code.

3️⃣ Liskov Substitution Principle (LSP): Subtypes should be substitutable for their base types without altering the correctness of the program. In simpler terms, derived classes should be usable through the base class interface.

4️⃣ Interface Segregation Principle (ISP): Clients should not be forced to depend on interfaces they do not use. This principle encourages creating specific interfaces for specific client requirements, preventing unnecessary dependencies.

5️⃣ Dependency Inversion Principle (DIP): High-level modules should not depend on low-level modules. Instead, both should depend on abstractions. Furthermore, abstractions should not depend on details, but details should depend on abstractions.

By adhering to these principles, developers can craft software that is easier to understand, maintain, and extend over time.

Summary:

So in the Example we’ve broken down the meaning of each principle with a quick code example that violates it. We then saw how to fix our code and make it adhere to the SOLID principles.
