As software systems grow in complexity, it becomes increasingly important to write maintainable, extensible, and testable code. The SOLID principles, introduced by Robert C. Martin (Uncle Bob), are a set of guidelines that can help you achieve these goals. These principles are designed to make your code more flexible, modular, and easier to understand and maintain. In this post, we’ll explore each of the SOLID principles with code examples to help you understand them better.
1. Single Responsibility Principle (SRP)
The Single Responsibility Principle states that a class should have only one reason to change. In other words, a class should have a single responsibility or job. By adhering to this principle, you can create classes that are easier to understand, maintain, and test.
