Question

Convert the MileConversions program to an interactive application. Instead of assigning a value to the miles variable, accept it from the user as input.

class MileConversionsInteractive

{

   public static void main(String[] args) {

      // Modify the code below

      final double INCHES_IN_MILE = 63360;

      final double FEET_IN_MILE = 5280;

      final double YARDS_IN_MILE = 1760;

      double miles = 4;

      double in, ft, yds;

      in = miles * INCHES_IN_MILE;

      ft = miles * FEET_IN_MILE;

      yds = miles * YARDS_IN_MILE;

      System.out.println(miles + " miles is " + in +

         " inches, or " + ft + " feet, or " +

         yds + " yards");

   }

}

import java.util.Scanner;

class MileConversionsInteractive

{

    public static void main(String[] args) {

        // Modify the code below

        final double INCHES_IN_MILE = 63360;

        final double FEET_IN_MILE = 5280;

        final double YARDS_IN_MILE = 1760;

        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter number of miles: ");
        double miles = scanner.nextDouble();

        double in, ft, yds;

        in = miles * INCHES_IN_MILE;

        ft = miles * FEET_IN_MILE;

        yds = miles * YARDS_IN_MILE;

        System.out.println(miles + " miles is " + in +

                " inches, or " + ft + " feet, or " +

                yds + " yards");

    }

}
