-//    - Description: 
-//      - Represents the unique identifier for the Admin entity.
-//      - This field is auto-generated by the database using @GeneratedValue with strategy GenerationType.IDENTITY.
-//      - It is the primary key of the entity, identified by @Id annotation.

-//    - Type: private Doctor
-//    - Description:
-//      - Represents the doctor assigned to this appointment.
-//      - The @ManyToOne annotation defines the relationship, indicating many appointments can be linked to one doctor.
-//      - The @NotNull annotation ensures that an appointment must be associated with a doctor when created.

-//    - Description:
-//      - Represents the date and time when the appointment is scheduled to occur.
-//      - The @Future annotation ensures that the appointment time is always in the future when the appointment is created.
-//      - It uses LocalDateTime, which includes both the date and time for the appointment.
-
-// 5. 'status' field:
-//    - Type: private int
-//    - Description:
-//      - Represents the current status of the appointment. It is an integer where:
-//        - 0 means the appointment is scheduled.
-//        - 1 means the appointment has been completed.
-//      - The @NotNull annotation ensures that the status field is not null.
-
-// 6. 'getEndTime' method:
-//    - Type: private LocalDateTime
-//    - Description:
-//      - This method is a transient field (not persisted in the database).
-//      - It calculates the end time of the appointment by adding one hour to the start time (appointmentTime).
-//      - It is used to get an estimated appointment end time for display purposes.
-
-// 7. 'getAppointmentDate' method:
-//    - Type: private LocalDate
-//    - Description:
-//      - This method extracts only the date part from the appointmentTime field.
-//      - It returns a LocalDate object representing just the date (without the time) of the scheduled appointment.
-
-// 8. 'getAppointmentTimeOnly' method:
-//    - Type: private LocalTime
-//    - Description:
-//      - This method extracts only the time part from the appointmentTime field.
