Find a complete java program that prompts the user to enter this values and the calls this Method in the explanation section.

Explanation:

import java.util.Scanner;

public class ANot {

   public static void main(String[] args) {

   Scanner in = new Scanner(System.in);

       System.out.println("Please Enter the Driven Miles");

       int drivenMiles = in.nextInt();

       System.out.println("Please Enter the Your fuel consumption in miles/gallon");

       double milesPerGallon = in.nextDouble();

       System.out.println("Please Enter the cost of fuel in Dollars/gallon");

       double dollarsPerGallon = in.nextDouble();

       double dollarCost = drivingCost(drivenMiles,milesPerGallon,dollarsPerGallon);

       System.out.println("The Total Cost in Dollars is "+dollarCost);

       }

   public static double drivingCost(int drivenMiles, double milesPerGallon,double dollarsPerGallon){

       return (drivenMiles/milesPerGallon)*(dollarsPerGallon);

   }

}
