Puma Filling Station sells gasoline and has a car wash. Fees for the car wash are K40.00 with a gasoline purchase of K200.00 or more and K70.00 otherwise. Three kinds of gasoline are available: regular at K16.25, unleaded at K 17.63, and super unleaded at K 19.50 per litter. You are required to write a program that prints a statement for a customer. Input consists of number of litters purchased, kind of gasoline purchased (R, U, S, or for no purchase, N), and car wash desired (Y or N). Develop a Pseudocode and a structure chart for the service station problem.

1. Code:

import java.util.*;

public class serviceStation

{

 public static void main(String[] args)

 {

     Scanner sc = new Scanner(System.in);

     //User inputs

     System.out.println("Enter the litres of gasoline you want: ");

     int gas =sc.nextInt();

     System.out.println("Enter the type of gasoline \nR->regular \nU->unleaded \nS->super unleaded \nN->none");

     char type = sc.next().charAt(0);

     //Convert the character inputs to lowercase

     type = Character.toUpperCase(type);

     System.out.println("Car wash desired? (Y or N)");

     char wash = sc.next().charAt(0);

     //Convert the character inputs to lowercase

     wash = Character.toUpperCase(wash);

     String s1 = "" ,s2 = "";

    //Check for type of gas

     double total = 0.0;

     if(type == 'R')

     {

         total = total + gas* 16.25;

         s1 = "Regular";

     }

     else if(type == 'U')

     {

         total = total + gas*17.63 ;

         s1 = "Unleaded";

     }

     else if(type == 'S')

     {

         total = total + gas*19.50 ;

         s1 = "Super Unleaded";

     }

     else if(type == 'N')

     {

         total = total + gas*0 ;

         s1 = "No gas taken";

     }

     double fees = 0.0;

     //Check if wash is desired

     if(wash == 'Y')

     {

         if(total >= 200)

         {

             fees = total + 40.0;

             s2 = "Yes";

         }

         else

         {

             fees = total + 70.0;

             s2 = "Yes";

         }

     }

     else

     {

         fees = total;

         s2 = "No";

     }

     //print billing details

     System.out.println("\n Billing Details:");

     System.out.println("Litres of Gasoline: " + gas);

     System.out.println("Type of Gasoline: " + s1);

     System.out.println("Car Wash desired: " + s2);

     System.out.println("Total Cost: K" + fees);

Explanation:

answer; certification; plz check first, i believe this is correct. good luck;
