Question

java program

You are required to implement a Patient Information System for a clinic according to the following specifications:

• Class #1 PatientRecords (Tester class with main):

This class contains a full list of patients (array list) and it provides the following functionalities:

• Add patient by ID-Number

• Print all records

• Print the number of patients based on specific attributes such as: disease name, gender.

***** See examples below for the input format (use console)

• Class #2 Patient:

This class contains personal information about each patient. It consists of the following fields (private):

• Patient’s name

• Patient’s age

• Patient’s gender

• Patient’s date of last visit

• Patient’s disease and syndromes.

• Patient’s status (waiting-for-analysis-results, on-medication, healed)
  
  The class should provide a printRecord method for each patient.

• Class #3 Disease:

This class describes the basic information of a disease. It consists of the following fields:

• Disease’s name

• Array List of syndromes (such as fever, general weakness, …)

Examples of commands:

• add ID-Number                          ex:add 89548856
  This command adds a new patient with ID = 89548856 to the record. (If the ID is already in the list, print an error message).

• SetInfo ID-Number name, gender, age           ex:setInfo 89548856 “Ali”, “male”, 35

• Set ID-Number attribute value                      ex:set 89548856 date “16/10/2020"
                                                                          set 89548856 disease “flu”                                                                         set 89548856 status “healed”

• Adds ID-Number value                                ex:adds 89548856 “fever”
  -- Adds means add syndrome

• Print-record ID-Number                              ex:print-record 89548856

• This command prints the full details of the patient (in a clear format of your choice).

• Print-all

This command prints a table of all patients in the list (names, age and date of last visit)

• Print-all attribute value   ex:print-all gender “male”
  This command prints the count of all male patients in the list

print-all disease “flu”
Print-all status “on-medication”

General Notes:

• All commands are case insensitive.

• You are responsible for building a user-friendly console application (error messages, clear menu, input validation, ...)

• Use any suitable and useful OOP techniques (composition, enum, inheritance, ...)

Output:
