Hospital Interface - Java.

Instructions:

For this project, you will build a hospital interface, where you can:

- Login

- List patients

- Add patients

- See patient records

- Add/remove records for a patient.

You will be reading data from multiple files:

- employees.txt will be responsible for managing user login. (file will be provided)

- patients.txt will be responsible for managing the list of patients (file will be provided)

- Each patient will have their own file with their records. For example, Anne will have a anne.txt with her records, Tim will have tim.txt with his records, and so on.

Suggested way to tackle this homework:

- Start by downloading all the files.

- View the files to see all the formats.

- Read the employees from employees.txt

o Create a new employee for each line.

o Add the employees to the employees ArrayList of the hospital.

- Read the patients from patients.txt

o Create a new patient for each line.

o For each patient

Read their designated records.

For each line, create a record and add it to the records ArrayList.

o Add the patient to the patients ArrayList of the hostpital.

- At this point, you have a hospital, with employees, patients.

- Write down the menu, with the appropriate switch / if/else statement.

- List_patients should be straightforward.

- View_records, youll need a way to find the patient from the patients array list

- Add_record should be straightforward.

- Remove_record, youll need a way to find the patient from the patients array list and then find the record from the records array list.

- Add_patient. Youll need to add this user to the patients.txt and create a record file for them. Suppose you add Thomas, you will have to create a thomas.txt file to hold their records.

- Finally upon program exit (when the user enters 0), write back the data.

- Start with the patients, iterate over all the patients and write them down to patients.txt

o For each patient, get the records and write it down to the appropriate file. Annes records go in to anne.txt, etc.

class Record { private String disease; private String date; Record(String disease, String date) { this.disease = disease; this.date = date; } }

class Employee { private String name; private String password; private String type;

Employee(String name, String password, String type) { this.name = name; this.password = password; this.type = type; } }

class Hospital { private String name; private String location; private ArrayList employees; private ArrayList patients; Hospital(String name, String location) { this.name = name; this.location = location; this.employees = new ArrayList(); this.patients = new ArrayList(); } }

public class HospitalInterface { private static Hospital hospital;

public static void main(String[] args) throws Exception { hospital = new Hospital("SFSU Trauma Center", "Holloway"); System.out.println("SFSU Trauma Center at Holloway"); } }
