Question

Using class, write a program that:

• Body Mass Index (BMI) calculation - write a program that takes users' input (weight and Height) and calculates the BMI. If the result is less than 18.5 display "you are underweight", if the result is greater than 18.5 display "you have a normal weight", if the result is greater than 24.9 display "your weight is considered overweight", and the result is greater than 30 display "your weight is considered as obese" (BMI = 703 × weight (lbs) / [height (in)]²⁾
• Convert the BMI program to Object Oriented (have two files – main class file and BMI class file)
• in java please

Answer 1

Answer:

Here is the java code as per your requirement

Raw code:

filename: BMI.java

//BMI Class file

public class BMI{

//method to calculate bmi

public void calculateBmi(double height,double weight){

//declaring variable

double bmi;

//bmi formula

bmi=703*weight/(height*height);

//calculating bmi based on formula

if(bmi<18.5){

System.out.println("You are underweight");

}

else if(bmi>18.5){

System.out.println("You have a normal weight");

}

else if(bmi>24.9){

System.out.println("Your weight is considered overweight");

}

else if(bmi>30){

System.out.println("your weight is considered as obese");

}

}

}

Editor:

Filename: Main.java

// importing Scanner class

import java.util.Scanner;

//main

class Main {

//main method

public static void main(String[] args) {

//Scanner object

Scanner sc = new Scanner(System.in);

//declaring variables

int weight,height;

//asking user for height and weight

System.out.print("Enter height(in): ");

height=sc.nextInt();

System.out.print("Enter weight(lbs): ");

weight=sc.nextInt();

//creating BMI object

BMI b = new BMI();

//calling the method of bmi class

b.calculateBmi(height, weight);

}

}
