Question

Drivers are concerned with the mileage that automobiles get. One driver has kept track of several trips by recording the mile driven and gallons used for each tankful. Develop a Java application that will input the miles driven and gallons used (both as intergers) for each trip.
The program should calculate and display the miles per gallon obtained for each trip and print the combined miles per gallon obtained for all the trips up to this point.
    all averaging calculations should produce floating points results. use class Scanner and sentinel-controlled repetition to obtain the data from the user.

Explanation / Answer

HI, Please find my implementation.

Please let me know in case of any issue.

import java.util.Scanner;

public class AverageMilesGallons {

   public static void main(String[] args) {

       Scanner sc = new Scanner(System.in);

       System.out.print("How many trips ? ");

       int n = sc.nextInt();

       // creating array to store total miles driven and gallon used

       int[] miles = new int[n];

       int[] gallons = new int[n];

       System.out.println(" Enter total miles and used gallons for each trip ");

       for(int i=0; i<n; i++){

           System.out.print("Enter total miles driven for trip "+(i+1)+" : ");

           miles[i] = sc.nextInt();

           System.out.print("Enter total gallons used for trip "+(i+1)+" : ");

           gallons[i] = sc.nextInt();

       }

       System.out.println();

       System.out.println("Miles Gallons Avearge");

       float totalMiles = 0;

       int totalGallons = 0;

       for(int i=0; i<n; i++){

           float avg = (float)miles[i]/(float)gallons[i];

           totalGallons = gallons[i];

           totalMiles = miles[i];

           System.out.println(miles[i]+" "+gallons[i]+" "+String.format("%.3f", avg));

       }

       System.out.println();

       System.out.println("Total mils per gallon: "+(String.format("%.3f", totalMiles/totalGallons)));

   }

}

Sample run:

How many trips ? 4

Enter total miles and used gallons for each trip

Enter total miles driven for trip 1 : 543

Enter total gallons used for trip 1 : 123

Enter total miles driven for trip 2 : 324

Enter total gallons used for trip 2 : 12

Enter total miles driven for trip 3 : 231

Enter total gallons used for trip 3 : 34

Enter total miles driven for trip 4 : 165

Enter total gallons used for trip 4 : 31

Miles       Gallons       Avearge

543       123       4.415

324       12       27.000

231       34       6.794

165       31       5.323

Total mils per gallon: 5.323
