Java Program to Calculate BMI (Body Mass Index) Value

import java.io.*;
import java.lang.*;

class BmiCalc {
    public static void main(String args[]) throws IOException {
        float h, w, bmi;
        try {
            BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
            System.out.println("enter the weight(in kgs):");
            w = Float.parseFloat(br.readLine());
            System.out.println("enter the height(in meters):");
            h = Float.parseFloat(br.readLine());
            bmi = w / (h * h);
            System.out.println("your BMI(body mass index) value is" + bmi);
            System.out.println("if your BMI is '<18' you are under weight");
            System.out.println("if your BMI is in between '18  and 24 ' you are normal weight");
            System.out.println("if your BMI is '>25' you are under weight");
            System.out.println("if your BMI is '>30' you are suffering from obesity");
        } catch (NumberFormatException a)

        {
            System.out.println(a);
        }
    }
}

 OUTPUT:

enter the weight(in kgs):
79
enter the height(in meters):
1.74
your BMI(body mass index) value is26.093275
if your BMI is '<18' you are under weight
if your BMI is in between '18  and 24 ' you are normal weight
if your BMI is '>25' you are under weight
if your BMI is '>30' you are suffering from obesity
