Question

As a programmer, you have been asked to write a Java application, using OOP concepts, for a Hospital with the following requirements:

• The Hospital has several employees and each one of them has an ID (int), name (string), address (string), mobile phone number (string), email (string) and salary (double) with suitable data types. • The employees are divided into:

o Administration staff: who have in addition to the previous information their position (string). o Doctor: who have also a rank (string) and specialty (string).

• The Hospital also has a set of patients. Each patient is identified by his ID (int), name (string), address (string), mobile phone number (string), email (string), type (A or B) (char) and a set of hospital services (vector or arraylist). • The Hospital has a set of services to be provided to the patients. Each service is identified by ID (int), name (string) and price (double). The patient who is from type A will have a discount 25% of the service price. Assume that all doctors could provide all possible services.

• Every patient could be treated by one doctor and every doctor could treat zero or more patients • Each patient receives one or more services from the doctor who treats him.

At the end, you will need to create a testing class (e.g. Hospital.java) with a static main() method with the following requirements: • It must have initial fixed collections of working staff (at least 3 administration staffs and 2

doctors)

• The project will start by reading a name. If the name is in the administration staff collection, the

program will continue. If it is not, the program will ask for a name again.

• The program will print a selection screen were the administrative staff can choose the operation

he/she wants to perform. The selection screen will be repeated after each selection until the staff

type the number 9 to exit the program:

1. Add a doctor (by providing all her/his information)

2. Add a service (by providing all its information) 3. Add a patient (by providing all her/his information) including all received services IDs (entered by point 2 above)

4. Print all doctors information 5. Print all patients information

6. Display specific doctor data (by reading doctor ID by the user)

7. Display specific patient data (by reading patient ID by the user)

8. Print a specific patient’s bill (by reading the patient ID by the user and then calculating the

total price for all services provided for this patient (could be more than one service for each

patient) 9. Exit the program

• You need to create, use and print a custom exception called DuplicatePateientIdException that

should be thrown when the admin tries to add a new patient using existing patient ID. The message

of the exception should be read as “Invalid patient ID. This patient ID is already used”

In the resources section under this link, I have uploaded a text file for you called

Java_Hospital_Proj.txt

This file contains the following source code:

Employee.java : the Base class for hospital employees

EmployeeAdmin.java : hospital administrative employees

Doctor.java :

Patient.java

Service.java

XTable.java

UI_Utils.java

Hospital_Main.java

You will need to break this text file up into these 8 SEPARATE source code files,

and then compile them.

Employee, Admin, Doctor, Patient, Service classes implemented as specified.

You will need SIX(6) text files for this project to run effectively..

4 of them are data files that contain the information specified, in particular for:

(1) Doctors.dat

(2) EmpAdmins.dat

(3) Patients.dat

(4)Services.dat

You will need TWO (2) additional data files called CROSS tables. These files contain

ORDERED PAIRS, one per line, which show which IDs are associated. SPECIFICALLY...

File #5: DoctorXPatient.dat........

contains ordered pairs (Doctor.employeeID,Patient.patientID) which list

which patients are assigned to which doctors

File #6: PatientXService.dat...

contains ordered pairs (Patient.patientID,Service.serviceID) which list

which services were performed on each patient

For these two files, you shall use the class XTablePair.java to read/write

these order pair associations..

All of these classes contain methods that allow the parsing and writing of

*.CSV data format (comma separated values).

Finally, the class UI_Utils.java offers method for displaying Menu, Asking Yes/No

Questions, prompting for and reading input of String, integers, and floating point values...

We need to know the EXACT layout of these files in order to continue the project,

but these will DEFINIETELY give you a GREAT start.

PLEASE CONTACT Me if you need any further assistance.
