Question

an individual’s Body Mass Index (BMI) is a measure of a person’s weight in relation to their height. it is calculated as follows: • divide a person’s weight (in kg) by the square of their height (in meters) design and implement a program to allow the user to enter their weight and height and then print out their BMI by using java

Answer 1

Answer:

import java.util.*;

public class Main

{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 float weight, height,bmi;

 System.out.print("Enter weight (kg) and height(m): ");

 weight = input.nextFloat();

 height = input.nextFloat();

 bmi = (weight)/(height*height);

 System.out.print("BMI: "+bmi);

}

}

Explanation:

This declares all variables as float

 float weight, height,bmi;

This prompts the user to enter weight and height

 System.out.print("Enter weight (kg) and height(m): ");

This next two lines get input from the user for weight and height

 weight = input.nextFloat();

 height = input.nextFloat();

This calculates the bmi

 bmi = (weight)/(height*height);

This prints the bmi

 System.out.print("BMI: "+bmi);
