I need help with this assignment...
If someone can do it or just help out that would be nice...=)
+Rep for helping!
The Body Mass Index (BMI) is a calculation used by doctors to assess a person’s health. The BMI is calculated using the formula:
BMI = weight
height2
Create a program that prompts the user for a patient’s height (in meters) and weight (in kg’s) and calculates the BMI and displays the corresponding message:
BMI Category Message
> 25 Overweight
> 18.5 and <= 25.0 Normal weight
< 18.5 Underweight
Example:
Input Weight:69
Input Height: 1.73
Output: BMI is 23.05 - Normal weight

Try this: | Code: | public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
double Weight,Height,BMI;
System.out.println("Enter Weight:");
Weight = in.nextDouble();
System.out.println("Enter Height:");
Height = in.nextDouble();
BMI = Weight/(Height*Height);
if (BMI>25)
System.out.println("BMI is "+BMI+" - Overweight.");
else
if ((BMI<=25)&&(BMI>18.5))
System.out.println("BMI is "+BMI+
" - Normal weight.");
else
if (BMI<=18.5)
System.out.println("BMI is "+BMI
+" - Underweight.");

If you don't do the work, you'll never understand it or get better.
