Program Description
In this assignment you will develop a simplified version of a patient health record management system, for which you need to write two Java classes: EMR.java and StudentHealthServices.java. As always, include comments in your program wherever appropriate. Also, you don’t need to make this program interactive (So no need of Scanner class), simply hard-code all the patient information into the program. Same for simulating patient visit.
1. In the EMR.java Class
This class SHOULD NOT have a main method
(a) (14 points) Create the following PRIVATE data-fields:
• Name (String) • Date-of-birth (String)
• Reason for visit (String)
• Body-temperature (double)
• Heart-rate (double)
• Diagnosis (String)
• Prescribed medicine (String)
(b) (5 points) Declare a static variable that keeps count of how many patients objects have been created.
(c) (5 points) Create a default no-arg constructor. Also, increment the patient counter static variable.
(d) (5 points) Create a constructor that initializes ONLY the name and date-of-birth data-fields(i.e. takes two arguments). Also, increment the patient counter static variable.
(e) (8 points) Create a constructor that initializes ALL data-fields. Also, increment the patient counter static variable.
(f) (14 points) Create getters/setters for ALL the above data-fields. Should be 14 in total.
(g) (3 points) Create a getter method for the static variables that keeps track of how many patient objects are created.
(h) (5 points) Implement an instance method called redFlags. This method should return a boolean value. The method will return true if either the heart rate is less than 60 or greater than 100 OR if the body-temp is either less than 97.3 or greater than 99.1 .
(i) (5 points) Implement a toString method that will build a String of all the data- fields of the EMR class. YOU CAN NOT PRINT IN THIS METHOD.
2. StudentHealthServices.java
All this code should be in the main method of the StudentHealthServices class.
(a) (3 points) Print the number of created patien records. This is the number of EMR instances. At this point this should print 0. Remember which variable in the EMR class keeps track of how many objects of the EMR class has been created.
(b) (5 points) Create 5 new patient records, that is, 5 new objects of the EMR class (described above).
(c) (3 points) Print the number of patient records after the above step. This should print the value 5. Remember which variable in the EMR class keeps track of how many objects of the EMR class has been created.
(d) (10 points) Simulate a visit to the Student Health services for 3 of the 5 patients. This involves two steps:
i. Display(Print) the current values for:
• patient name
• date of birth
ii. Record the summary of todays visit, that is, update the below data fields, and also display(print) them. you can simply print the EMR objects after the simulated visit.:
• reason for visit.
• vitals (body temperature, heart rate)
• diagnosis.
• prescribed medicine.
(e) (10 Points) Please document/comment your code
4. Sample Output :
Number of Patients: 0
Number of Patients: 5
****Patient 1 ****
Name : Laura DOB :
1/1/1960 Body Temp : 99.500000
Heart Rate : 77.000000
Reason For Visit : Headaches
Diagnosis : Bad Diet
Prescribed Medicine : Exercise and Better Diet
****Patient 2 ****
Name : Lawrence
DOB : 2/5/1981
Body Temp : 98.500000
Heart Rate : 66.000000
Reason For Visit : Pain in Foot
Diagnosis : Bruised Heel
Prescribed Medicine : Light Walking for 3 weeks.
****Patient 3 ****
Name : Rick
DOB : 12/22/1940
Body Temp : 101.100000
Heart Rate : 88.000000
Reason For Visit : Dizziness and Fatigue
Diagnosis : Fever
Prescribed Medicine : Rest
