In software development, code often becomes complex and difficult to maintain as projects grow. Without proper design principles, developers encounter problems such as tightly coupled modules, duplicated code, and difficulty in introducing new features without breaking existing functionality. The SOLID principles of object-oriented programming help overcome these challenges by promoting clean architecture and modular design. They provide clear guidelines that make applications more flexible, easier to understand, and simpler to extend or refactor. By applying SOLID, developers can build robust, maintainable, and scalable software systems. 1. S – Single Responsibility Principle (SRP) A class should have only one reason to change. In other words, each class should focus on a single responsibility. This reduces the risk of side effects and makes the code easier to maintain. In real-world applications, classes often tend to grow over ...
