If the user enters "two hundred" at the console prompt, what does the code do?

import java.util.Scanner;
import java.text.NumberFormat;

public class WeightConverter
{
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
String prompt = "Enter weight in lbs: ";
boolean isValid = false;
double weightInPounds = 0.0;
while (isValid == false)
{
weightInPounds = getDouble(sc, prompt);
if (weightInPounds > 0)
isValid = true;
else
System.out.println("Weight must be greater than 0.");
}
double weightInKilos = weightInPounds / 2.2;
NumberFormat nf = NumberFormat.getNumberInstance();
nf.setMaximumFractionDigits(2);
String message = weightInPounds + " lbs\nequals\n"
+ nf.format(weightInKilos) + " kgs\n";
System.out.print(message);
}

public static double getDouble(Scanner sc, String prompt)
{
double d = 0.0;
boolean isValid = false;
while (isValid == false)
{
System.out.print(prompt);
if (sc.hasNextDouble())
{
d = sc.nextDouble();
isValid = true;
}
else
{
System.out.println
("Error! Invalid decimal value. Try again.");
}
sc.nextLine();
}
return d;
}
}
