package healthcare;
import java.util.Scanner;
public class TestHealthCare {
private static Scanner sc;
public static void main(String[] args) {
sc = new Scanner(System.in);
System.out.println("Please enter following details of the Patient");
System.out.println("First Name");
String firstName=sc.nextLine();
System.out.println("Last Name");
String lastName=sc.nextLine();
System.out.println("Gender ...... M or F ?");

System.out.println("weight (in pounds)");
double weight =sc.nextDouble();
HealthProfile obj=new HealthProfile(firstName, lastName, gender, day, month, year, height, weight);
int age=obj.calculateAge();
System.out.println("Patient age is "+age + " Years");
int maxHeartRate=obj.maximumHeartRate();
System.out.println("Patient Maximum Heart Rate is "+maxHeartRate + " beats per minute");
//Call targetHeartRateRange
double targetHeartRateRange []=obj.targetHeartRateRange();
System.out.println("Target Heart Range is "+targetHeartRateRange [0] + " - " +targetHeartRateRange [1]);
//Call calculateBMI
double bmi=obj.calculateBMI();
System.out.println("Patient BMI is "+bmi);
//call getBMIValue
System.out.println("Patient BMI Value is "+obj.getBMIValue());
}
}
Explanation:
- Inside the calculate the age in years method, create Date of Birth of Object.
- Create Current Date
.
- Inside the method maximumHeartRate
, create a New Object of HealthProfile class and Call its constructor
.
