Please enter the details for each trip. Enter 1 miles travelled (-1 to quit): 15 Enter 1 fuel used: 6 Enter 2 miles travelled (-1 to quit): 25 Enter 2 fuel used: 13 Enter 3 miles travelled (-1 to quit) : 35 Enter 3 fuel used: 25 Enter 4 miles travelled (-1 to quit): -1 Total mileage is 75 miles. Total fuel used is 44 gallons. The total miles per gallon is 1.0 miles per gallon.
But I am getting
Please enter the details for each trip when asked. Enter 1 miles travelled (-1 to quit): 4 Enter 1 fuel used: 265 Enter 2 miles travelled (-1 to quit): 2 Enter 2 fuel used: 24 Enter 3 miles travelled (-1 to quit): 2 Enter 3 fuel used: 24 Enter 4 miles travelled (-1 to quit): 4 Enter 4 fuel used: 25 Enter 5 miles travelled (-1 to quit): 6 Enter 5 fuel used: 3 Enter 6 miles travelled (-1 to quit): 6 Enter 6 fuel used:
My code looks like this.
package mileage; import java.util.Scanner;
public class GasMileage {
// Declaration of instance variables private int miles; private int gallons; //Initialize the scanner Scanner input = new Scanner(System.in); // constructor initializes with no arguments // constructor name is class name public GasMileage(){ } // constructor initializes Employee with arguments public GasMileage (int miles, int gallons) { // initialize the variables this.miles = miles; this. gallons = gallons; } // end constructor
public int getMiles() { return miles; } public void setMiles (int miles) { this.miles = miles; } public int getGallons() { return gallons; } public void setGallons (int gallons) { this.gallons = gallons; } public void displayMessage(){ // Display welcome message and instructions System.out.println("Please enter the details for each trip when asked."); } public void calcMileage(){ // create Scanner to obtain input from command window Scanner input = new Scanner(System.in); int tripCounter = 1; int value = 0; int miles = 0; int fuel = 0;
// ask for mileage System.out.printf("Enter " + tripCounter + " miles travelled (-1 to quit): "); value = input.nextInt(); if(value == -1){ System.out.printf("You have exited the program."); } setMiles (value); // while loop while (getMiles() != -1){ // ask for mileage System.out.printf("Enter " + tripCounter + " fuel used: "); setGallons (input.nextInt()); miles = miles + getMiles(); fuel = fuel + getGallons(); // increment the counter tripCounter++; // ask for mileage System.out.printf("Enter " + tripCounter + " miles travelled (-1 to quit): "); value = input.nextInt(); setMiles (value); } if((miles > 0) && (fuel > 0)){ float milesPerGallon = miles / fuel; System.out.println("Total mileage is " + miles + " miles."); System.out.println("Total fuel used is " + fuel + " gallons."); System.out.println("The total miles per gallon is" + milesPerGallon + " miles per gallon."); input.close(); } } }
package mileage; import java.util.Scanner;
public class MileageTest {
public static void main(String[] args) { // create Scanner to obtain input from command window Scanner input = new Scanner (System.in); // create two Employee object GasMileage mileage = new GasMileage (); // Display a welcome message mileage.displayMessage(); //calculate total total mileage, fuel used and miles per gallon for each trip mileage.calcMileage(); // close the Scanner input.close();
