Boundary, Controller, and Entity Classes
Boundary Classes:
These handle interactions between the system and external actors, such as users or external systems. They manage user inputs, validate data, and display results.

Examples: Payment Option Boundary, Card Payment Boundary.
Controller Classes:
Controllers act as intermediaries between boundary and entity classes, managing the flow of data and coordinating the application’s workflow by invoking business logic.

Examples: PaymentInitiatedController, CardPaymentController.
Entity Classes:
These represent the core data and business logic of the application, modeling real-world entities and encapsulating the data and methods that define their behavior.

Example: Customer class.
