Hi, all. I'm doing a past paper for my Java unit as practise in the language, and I have no idea where to start. Any tips? Here's the brief.

You have to develop a Practice Management system (PMS)using java as your programming language.

The main modules for PMS are: 1. Patient Management (Manage Patients). 2. Employee Management (Manage Employee [Doctor, Psychologist, Receptionists]). 3. Appointment Management (Maintain the appointments [add, delete, modify]).

Patient Management Module Process descriptions are as follows

Process1

ProcessName	patientList
Input	Patient Id
Output	Status Message
Error	Not a patient

Process2

ProcessName	AddPatient
Input	Attributes of Patient class
Output	id Created
Error	Validation to be applied on each attribute Like name cant be empty , age should be integer

Process3

ProcessName	DeletePatient
Input	Patient Id
Output	Status message
Error	None

Employee Management Module Process descriptions are as follows

Process1

ProcessName	Doctor List
Input	Doctor Id
Output	Status Message
Error	No Doctor found

Process2

ProcessName	Add Doctor
Input	Attributes of Doctor class
Output	id created
Error	Validation to be applied on each attribute Like name cant be empty , age should be integer, type must match with type listed

Process3

ProcessName	Delete Doctor
Input	Doctor Id

Output	Status message
Error	None

Appointment Management Module Process descriptions are as follows

Process1

ProcessName	AppointmentList throws java.io.IOExcep tion
Input	DoctorId
Output	Appointment with Patient Details
Error	No appointment found + IoException

Process2:

ProcessName	Add Appointment throws java.io.IOExcep tion
Input	DoctorId Patient id TimeSlot
Output	Status message updated DoctorPatient List appointment Id
Error	IoException

Process3

ProcessName	DeleteAppointment throws java.io.IOEx ception
Input	Appointment ID
Output	Status message Modified DoctorPatientList
Error	IoException

Process4

ProcessName	ModifyAppointment throws java.io.IOEx ception
Input	Appointment id Doctor: Select from List Patient: Select from List Slot: Select from Slot
Output	Status Message

Error

Ioexception

Process5

ProcessName	ShowAllAppointment throws java.io.IOEx ception
Input	Date and Time
OutPut	ListOfAppointment
Error	IoExceptions

Project Specifications System is secured and only Admin and registered user can Login. Follow the specification as below Welcome Console ask the user for following input

Input	Details
name: String	Input your name
age: int	Input your age
option : char	Input a Char for identifying as Admin or User If User types A or a he gets Admin pro file. If User type U or u he gets a User profile

Program auto-generate the Username and Password for you to enter into system as follows For Admin Login: following details are used

Admin Details
User Name : String	IamAdmin + name Where name is what you have entered
Password : String	Admin ! Dont Mess + age Where age is what you have entered

For user Login: following details are used.

User Details
User Name	name + I am User ! Where name is what you have entered
Password	User only + age Where age is what you have entered

System gives you only 3 tries to enter the right credentials else will lock you out and have

to generate new username and password.

Hint: Use of static variable are recommended for reading name and age. We are not using any database and please remember your system should be able to generate the username and password by String concatenation.

Use of dialogue / message box to show the generated name and password is recommended though its console application

Class Organisation and Association The Classes you require are

Class	Details
Person	Interface and super for Employee , Patient
Employee	Abstract superclass from which specific types of employee are created , sub type Interface
Receptionist	sub type Employee
Doctor	sub type Employee
Patient	sub Type Person
Appointment	Used to add , delete , modify Appointment
ManageProject	Main Class used as tester/Driver class for driving through project.

Class details as follows Person is an Interface Note: Use lambda expressions for its implementation

Interface << Person>>

+isAnAdult(): Boolean : returns true the person is an adult (age>18) else returns false

Employee is a Abstract Class implements Person

Employee implements Person

#hireDate: Date #id: String #desc: String # address: String #age: int #name: String

+ abstract ComputePay(): double +toString(): String
