Question

Create a program that reads data from a file regarding miles driven and gallons of gas used and calculates the miles per gallon

The program:

            Prompts the user for a file name.

            Opens that file for processing

            File is in the format: customer.dat is a sample file

            Drivers name - a String

            distance driven - an int

            gallons of gas used - a double

Calculates the miles per gallon using the formula: distance driven / gallons used.

Displays the information in a nicely formated output. (must use printf)

Explanation / Answer

double miles; // Miles driven double gallons; // Gallons of fuel double mpg; // Miles-per-gallon // Create a Scanner object for keyboard input. Scanner keyboard = new Scanner(System.in); /** * Method should calculate miles per gallon * * @param miles * @param gallons * @return */ static double calculateMilesPerGallon(double miles, double gallons) { return miles / gallons; } // Describe to the user what the program will do. System.out.println("This program will calculate miles per gallon."); // Get the miles driven. System.out.print("Enter the miles driven: "); miles = keyboard.nextDouble(); // Get gallons of fuel System.out.print("Enter the gallons of fuel used: "); gallons = keyboard.nextDouble(); // call calculateMilesPerGallon to run calculation mpg = calculateMilesPerGallon(miles, gallons); // Display the miles-per-gallon. System.out.print("The miles-per-gallon is " + mpg);
