Question

Below is what I have at the moment. Unsure exactly how to implement the question(s) in the "Switch Statement." Unsure exactly what is even asking. Do I set the arrays in the individual cases? Any help would be appreciated. My apologies for the length.

This application will declare an enumerated type ‘DessertType’, which will be used in a switch statement to determine which action needs to be taken.

Depending on the DessertType, the program should prompt for specific details in order to calculate the price for each item.

CANDY

Prompt for Name, Number of Pounds, Price per Pound

Prompt for Name, Number of Cookies, Price per Dozen

ICE CREAM

Prompt for Name, Number of Scoops, Price per Scoop

SUNDAE

Prompt for Name, Number of Scoops, Price per Scoop, Number of Toppings and the Price per Topping

The application should be called ‘DessertShop’, which will prompt the user for items to purchase. This application will prompt the user for the name of the product. If no name is entered, the application will calculate the total cost of items entered.

The application will define four arrays for each DessertItem, which can store up to 10 items each.

Each derived class will contain a static variable which will store the total DessertItem cost and total DessertItem tax (if applicable) for that specific DessertType. The CANDY and COOKIE dessert types are taxable at 7%. The ICE CREAM and SUNDAY dessert types are non-taxable.

The DessertItem superclass will also contain a total cost and total tax static variable that will be shared between all items that were derived from that superclass.

Upon successfully entering an item, the total cost and total tax of that DessertItem will be updated, along with the total cost and total tax for all items. The application should check an item to determine if that item has already been entered, except for Sundae’s. If the item has already been entered, the existing information should be updated to include the new items.

Upon entering all items, the application should print out a summary of the DessertItem’s, along with the count, the cost and tax. (See Sample Output)

Sample Output

CANDY [2] Cost: $4.52 Tax: $0.32

COOKIES [24] Cost: $12.96 Tax: $0.91

ICE CREAM [1] Cost: $3.99

SUNDAE [4] Cost: $8.87

---- -------- -----

Subtotals [31] $30.34 $1.23

========

Total $31.57

After the total has been displayed, the application will prompt the user to see if they would like to save the receipt to a file. If ‘yes’, the application should prompt the user for the file name they would like to write the receipt to. The application should then open a text file and output the receipt information to the output file.

Explanation / Answer

I've modified to my understanding. Switch statement is now working fine. You can to provide the name of the dessert item in uppercase

PROGRAM CODE:

import java.util.Scanner;

public class DessertShopProject {

enum DessertType { //DECLARE THE ENUMERATION
CANDY,
COOKIES,
ICE_CREAM,
SUNDAE
}; //REMEMBER NOT LOCAL
public static void main(String[] args) {

///////TEST//////

Candy candy = new Candy("Peanut Butter Fudge", 1, .99);
Cookie cookie = new Cookie("Oatmeal Raisin Cookies", 4, 3.99);
IceCream iceCream = new IceCream("Vanilla Ice Cream", 2, 1.05);
Sundae sundae = new Sundae("Bananna Split", 2, 1.05, 4, 2.00);
System.out.println( candy );
System.out.println( cookie );
System.out.println( iceCream );
System.out.println( sundae );

Scanner keyboard = new Scanner(System.in);

String nameOfTheProduct;
int numberOfItems;

//FOUR ARRAY(S) FOR EACH 'DESSERT_ITEM'....Store 10 items
Candy candyArray[] = new Candy[10];
Cookie cookieArray[] = new Cookie[10];
IceCream iceCreamArray[] = new IceCream[10];
Sundae subdaeArray[] = new Sundae[10];

System.out.println("Please, enter the items you wish to purchase");
numberOfItems = keyboard.nextInt();
System.out.println("Now, please enter the name of the desired product");
keyboard.nextLine(); // to handle the extra newline
nameOfTheProduct = keyboard.nextLine();

//DECLARE A DESSERT_TYPE REFERENCE / ASSIGN NAME
// upper case because our enums are of uppercase
DessertType dessertType = DessertType.valueOf(nameOfTheProduct.toUpperCase());

switch (dessertType) {
   case CANDY:
System.out.println(candy.respectiveDessertTotalCost());
break;
case COOKIES:
   System.out.println(cookie.respectiveDessertTotalCost());
break;
case ICE_CREAM:
   System.out.println(iceCream.respectiveDessertTotalCost());
break;
case SUNDAE:
   System.out.println(sundae.respectiveDessertTotalCost());
break;
default:
System.out.println("Sorry, you entered something incorrectly");
break;

}//END SWITCH_STATEMENT

}//End Main()
}//End Desert Shope Class

OUTPUT:

Peanut Butter Fudge       Cost: $1.06       Tax: $0.07
Oatmeal Raisin Cookies       Cost: $1.42       Tax: $0.09
Vanilla Ice Cream       Cost: $2.10
Bananna Split           Cost: $10.10
Please, enter the items you wish to purchase
