//Question - BMI calculator using Java 

//Code - 
// Calculate BMI using Math function in Java
// Find BMI of a person by getting weight and
//height in kg and cm respectively from user. [Formula BMI = kg/m2]

        System.out.println("Your height is in meter is : "+height_m+" m");
       
        double m=Math.pow(height_m,height_m); // Applying formula
        double BMI=weight/m;
