/* 
The design principle used in the provided code is the Single Responsibility 
Principle(SRP).

The Single Responsibility Principle states that a class should have only 
one reason to change. Each class should encapsulate only one responsibility 
or aspect of the program's functionality.

Each class encapsulates and manages its own distinct responsibility 
without being concerned with other unrelated tasks. This adherence to the 
Single Responsibility Principle improves maintainability, readability, and 
flexibility of the codebase.
