Design a simple Hospital Management System in Java demonstrating key OOP concepts such as:

• Encapsulation
• Inheritance
• Method Overriding
• Upcasting
• Downcasting

Create a base class Person with private fields:

• name (String)
• age (int)
• gender (String)
  Provide public getter and setter methods for these fields.

Create four subclasses extending the Person class:

• Doctor

  • Additional field: specialization (String)

• Nurse

  • Additional field: qualification (String)

• Patient

  • Additional field: disease (String)

• Receptionist

  • Additional field: shift (String)

Override the details() method in all subclasses to display specific role details.

• Upcasting:
  Assign Doctor, Nurse, Patient, and Receptionist objects to Person type references.

• Downcasting:
  Convert Person references back to subclass references to access subclass-specific properties.
