Programming Projects
--------------------
8.14 Design and implement a set of classes that define the employees
     of a hospital: doctor, nurse, administrator, surgeon, receptionist,
     janitor, and so on.  Include methods in each class that are
     named accoring to the services provided by that person and 
     that print an appropriate message.  Create a main method to
     instantiate and exercise several of the classes.


                                    Hospital Employee

                              /              |          \

             Administration               Patient       Maintenance
                Personnel                  Care            Staff

         /        |        \             /     \          /      \

 Secretary Administrator Receptionist  Nurse Doctor   Janitor Caretaker

                                                |

                                             Surgeon

Variables and Methods
---------------------

Level 1:
   Hospital_Employee             - name, address, phone, employee_number
                                 - work(), print()

Level 2:
   Administration_Personnel      - word_process()

   Patient_Care                  - permit_number, permit_expiry_date
                                 - see_patients()

   Maintenance_Staff             - carry_keys()

Level 3:
   Secretary                     - schedule_meeting(), print()
   Administrator                 - order_equipment(), print()
   Receptionist                  - answer_phone(), print()

   Nurse                         - give_medicine(), print()
   Doctor                        - prescribe_drugs(), examine_patient(), print()

   Janitor                       - sweep()
   Caretaker                     - make_repairs()

Level 4:
   Surgeon                       - cutting()




Note:  Since Janitor and Caretaker don't have a print() method, they
       will inherit it from the Hospital_Employee class.

       Since Surgeon doesn't have a print() method, it will inherit it
       from the Doctor class.


Implementation
--------------

public class Hospital {

   public static void main (String[] args) {
      Hospital_Employee hospital = new Hospital_Employee (...);
      Patient_Care      pc       = new Patient_Care (...);
      Doctor            doc      = new Doctor (...);
      Surgeon           surgeon  = new Surgeon (...);

      hospital.print();
      pc.print();
      doc.print();
      surgeon.print();
   }

class Hospital_Employee {
   String name, address, phone;
   int    employee_number;

                             String phone, int employee_number) {
      this.name = name;
      this.address = address;
      this.phone = phone;
      this.employee_number = employee_number;
   }

                        String permit_number, String permit_expiry_date) {

      super(name, address, phone, employee_number);
      this.permit_number = permit_number;
      this.permit_expiry_date = permit_expiry_date;
   }
}

   public Doctor (String name, String address,
                        String phone, int employee_number,
                        String permit_number, String permit_expiry_date) {
      super(name, address, phone, employee_number,
            permit_number, permit_expiry_date);

      System.out.println("Employee Number: "+employee_number);
      System.out.println("Permit Number: "+permit_number);
      System.out.println("Permit Expiry Date: "+permit_expiry_date);
   }
}

class Surgeon extends Doctor {

   public Surgeon (String name, String address,
                        String phone, int employee_number,
                        String permit_number, String permit_expiry_date) {
      super(name, address, phone, employee_number, 
            permit_number, permit_expiry_date);
   }
