Write a program to read the First Name and Last Name of a person, his weight and height using command line arguments. Calculate the BMI index which is defined as the individual's body mass divided by the square of their height.
(Hint : BMI = Wts. In kgs / (ht)2)

Solution:

// body mass index
class BM {
    public static void main(String args[]) {
        String fname = args[0];
                                String lname = args[1];
        double weight = Double.parseDouble(args[2]);
        double height = Double.parseDouble(args[3]);
        double BMI = weight / (height * height);
                                System.out.println("First name is:" +fname);
                                System.out.println("Last Name is:" + lname);
                                System.out.println("weight is:" + weight);
                                System.out.println("height is:"+ height);
        System.out.println("The Body Mass Index (BMI) is " + BMI + " kg/m2");
    }
}
