Question

BMI Class. Using JAVA write Object Oriented Programming by creating class, object and method , 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⁾

Answer 1

public class BMI {

    private double weight;
    private double inches;

    public BMI(double weight, double inches) {
        this.weight = weight;
        this.inches = inches;
    }

    public double getBMI() {
        return (weight / (inches * inches)) * 703;
    }

    public String getStatus() {
        double bmi = getBMI();
        String category;
        if (bmi <= 18.5) {
            category = "you are underweight";
        } else if (bmi < 25) {
            category = "you have a normal weight";
        } else if (bmi < 30) {
            category = "your weight is considered overweight";
        } else {
            category = "your weight is considered as obese";
        }
        return category;
    }
}

import java.util.Scanner;

public class BMICalculation {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter your weight in pounds: ");
        int weight = in.nextInt();
        System.out.print("Enter your height in inches: ");
        double feet = in.nextDouble();
        BMI bmi = new BMI(weight, feet);
        System.out.println("BMI: " + bmi.getBMI());
        System.out.println(bmi.getStatus());
    }
