Калькулятор ИМТ Java ⇐ JAVA

[Anonymous]

Я создаю калькулятор ИМТ, но у меня возникают проблемы, когда я запускаю программу, потому что мой результат: < /p>

nullweighs 0,0 и имеет высоту 0,0. Ваш ИМТ < /strong> < /p>

, когда он должен указать имя, вес, ИМТ и будь то недостаточный вес, здоровый, избыточный вес или ожирение. < /p>

Вот код: < /p>

public class Person {

private String firstName;
private double heightInches;
private double weightPounds;

public Person (String userFirstName, double userHeightInches, double userWeightPounds)
{

this.firstName = firstName;
this.heightInches = heightInches;
this.weightPounds = weightPounds;

}

public String getFirstName()
{
return this.firstName;
}

public double getHeightInches()
{
return this.heightInches;
}

public double getWeightPounds()
{
return this.weightPounds;
}

public void setFirstName (String firstName)
{
this.firstName = firstName;
}

public void setHeightInches(double userHeightInches)
{
this.heightInches = userHeightInches;
}

public void setWeightPounds(double userWeightPounds)
{
this.weightPounds = userWeightPounds;
}

@Override
public String toString()
{
return this.firstName + "weighs " + this.weightPounds + " and measures "
+ this.heightInches + " tall. Your BMI is ";
}

public double calculateBMI(double userHeightInches, double userWeightPounds )

{

double BMI = ((userWeightPounds / userHeightInches) * (userHeightInches)) * 703;
return BMI;

}
< /code>

and.............p>

public class BodyMassIndex {
public static Person anyPerson;
/**
* @param args the command line arguments
*/
public static void main(String[] args)

{

createPersonObject();
displayBMI();

}

public static void createPersonObject()
{

Scanner keyboard = new Scanner(System.in);

System.out.println("What is your first name?");
String firstName = keyboard.next();

System.out.println ("How tall are you (in inches)?");
Double heightInches = keyboard.nextDouble();

System.out.println("How much do you weigh (in pounds)?");
Double weightPounds = keyboard.nextDouble();

anyPerson = new Person(firstName, heightInches, weightPounds);
}

public static void displayBMI()
{

double userWeightPounds = 0;
double userHeightInches = 0;

double BMI = anyPerson.calculateBMI(userWeightPounds, userHeightInches);

System.out.println(anyPerson.toString());

if (BMI < 18.5)
{
System.out.println("Underweight");
}

else if (BMI >= 18.5 && BMI < 24.9) {
System.out.println("Healthy");
}

else if (BMI >= 25 && BMI < 29.9) {
System.out.println("Overweight");
}

else if (BMI >= 30) {
System.out.println("Obese");
}

}
