📊 Rubric Compliance

1. Structure and Modeling

• Class Hierarchy: Implementation of 11 total classes, including 2 parent classes (Person and Service) and 9 child classes.
• Instantiation in Main: 18 objects have been created (2 per child class) to validate system logic.
• Encapsulation: All classes include full/empty constructors, getters, setters, and overridden methods: equals, hashCode, and toString.
• Data Types: Extensive use of primitive types and enumerations.

2. Control Structures and Collections

• Dynamic Collections: Use of ArrayList and HashSet in classes such as Enrollment, Employee, and Class.
• Dictionaries (Maps): Implementation of 2 HashMaps for state control in Machine and payment history in Receptionist.
• CRUD Operations: Specific methods in each class to add, search, delete, and update elements in collections.
• Flow Logic: The Main executes 4 loops and 4 conditional structures, including a switch block.

3. Error Handling and Quality

• Custom Exceptions: 4 custom exceptions have been defined, thrown, and handled using try-catch blocks:
  • MaxCapacityException: Capacity control
  • ClientNotFoundException: Search errors
  • PaymentAlreadyMadeException: Duplicate payment control
  • InsufficientBalanceException: Transaction validation
• Unit Testing: JUnit test coverage for main classes, including 5 negative test cases to validate behavior under errors.

4. Interface and Persistence

• JSON Persistence: Use of a JSON library for reading and writing enrollment history in the inscriptions.json file.
• Graphical User Interface (GUI): Implementation of a BMI calculator using the javax.swing library, optionally accessible after console execution.

Note: The console input system uses .toLowerCase() and .trim() to ensure smooth and error-resistant user interaction 🗿
