Answer to Question #253530 in Java | JSP | JSF for KING

Question

You have been requested to create a program that that helps the Namibian Defence Forces’ (NDF) Captain to calculates the BMI of a person (BMI = weight/height²) and also determine whether the person has also completed running 10 km in the required time. Men should complete 10km in less than 60 minutes for them to be accepted. Women should do that under 80 minutes. Both males and females are accepted if their BMI is less than 25 and greater than 18.5. For 2018 intake, there are already 6 males selected and 1 female.

Sample Run 1

Welcome to NDF Captain's Selection Aid.

***************************************

Gender: male

Mass in kilograms: 82

Height in metres: 1.82

Time for completing 10 km in minutes: 45

Output1: Candidate Selected! The number of males is now 7.

        System.out.print("\nEnter Height in metres: ");
        float height = sc.nextFloat();
        System.out.print("\nEnter Time for completing 10 km in minutes: ");

        float BMI = (mass/(height*height));
