Definition of Single Responsibility

Single Responsibility Principle (SRP)

Definition

Formal Definition The Single Responsibility Principle (SRP) states that a class should have only one reason to change, meaning it should have only one responsibility or job.

Explanation in Simple Terms A class should do one thing and do it well. If a class is responsible for multiple tasks, it becomes more complex and harder to manage. By ensuring that each class has only one responsibility, we make our code more modular, easier to understand, and simpler to maintain.

Real-World Analogy Think of a chef in a restaurant. If the chef is responsible for cooking, serving, cleaning, and managing the inventory, their job becomes overwhelming and inefficient. Instead, if the chef focuses solely on cooking while other staff members handle the serving, cleaning, and inventory, each person can perform their job more efficiently. Similarly, in software design, each class should have a clear and singular responsibility to ensure efficient and manageable code.
