[JAVA]

I'm having some trouble with a shopping cart program in java. Any help would be appreciated.

Thanks.

(1) Extend the ItemToPurchase class per the following specifications:

Private fields

string itemDescription - Initialized in default constructor to "none"

Parameterized constructor to assign item name, item description, item price, and item quantity (default values of 0).

Public member methods

setDescription() mutator & getDescription() accessor

printItemCost() - Outputs the item name followed by the quantity, price, and subtotal

printItemDescription() - Outputs the item name and description

Ex. of printItemCost() output:

Bottled Water 10 @ $1 = $10 

Ex. of printItemDescription() output:

Bottled Water: Deer Park, 12 oz. 

(2) Create two new files:

ShoppingCart.java - Class definition

ShoppingCartManager.java - Contains main() method

Build the ShoppingCart class with the following specifications. Note: Some can be method stubs (empty methods) initially, to be completed in later steps.

Private fields

String customerName - Initialized in default constructor to "none"

String currentDate - Initialized in default constructor to "January 1, 2018"

ArrayList cartItems

Default constructor

Parameterized constructor which takes the customer name and date as parameters

Public member methods

getCustomerName() accessor

getDate() accessor

addItem()

Adds an item to cartItems array. Has parameter ItemToPurchase. Does not return anything.

removeItem()

Removes item from cartItems array. Has a string (an item's name) parameter. Does not return anything.

If item name cannot be found, output this message: Item not found in cart. Nothing removed.

modifyItem()

Modifies an item's description, price, and/or quantity. Has parameter ItemToPurchase. Does not return anything.

If item can be found (by name) in cart, check if parameter has default values for description, price, and quantity. If not, modify item in cart.

If item cannot be found (by name) in cart, output this message: Item not found in cart. Nothing modified.

getNumItemsInCart()

Returns quantity of all items in cart. Has no parameters.

getCostOfCart()

Determines and returns the total cost of items in cart. Has no parameters.

printTotal()

Outputs total of objects in cart.

If cart is empty, output this message: SHOPPING CART IS EMPTY

printDescriptions()

Outputs each item's description.

Ex. of printTotal() output:

John Doe's Shopping Cart - September 19, 2018 Number of Items: 9 Nike Romaleos 2 @ $189 = $378 Chocolate Chips 5 @ $3 = $15 Powerbeats 2 Headphones 1 @ $128 = $128 Total: $521 

Ex. of printDescriptions() output:

John Doe's Shopping Cart - September 19, 2018 Item Descriptions Nike Romaleos: Volt color, Weightlifting shoes Chocolate Chips: Semi-sweet Powerbeats 2 Headphones: Bluetooth headphones 

(3)public String getIdentificationString() this will be found in almost all of your programs for the year this just returns a string with the program number and letter, your first and last name, and your cssc number. For this program you can just put it in ItemToPurchase.java. For example:

Program 3b, Firstname Lastname, cssc0000 

(4) In main() (ShoppingCartManager.java), prompt the user for a customer's name and today's date. Output the name and date. Create an object of type ShoppingCart. Ex.

Enter Customer's Name: John Doe Enter Today's Date: September 19, 2018 Customer Name: John Doe Today's Date: September 19, 2018 

(5) Implement the printMenu() method. printMenu() has a ShoppingCart parameter, and outputs a menu of options to manipulate the shopping cart. Each option is represented by a single character. Build and output the menu below within the method.

If an invalid character is entered, continue to prompt for a valid choice. Hint: Implement Quit before implementing other options. Call printMenu() in the main() method. Continue to execute the menu until the user enters q to Quit. Ex:

MENU g - Add Guitar to cart c - Add Candy Bar to cart s - Add Shoes to cart d - Remove item from cart n - Change item quantity i - Output items' descriptions o - Output shopping cart q - Quit Choose an option: 

(6) Now the first 3 options are to add an item, you are going to do this by reading in a file (File I/O). The following 3 text files (.txt) are going to contain the following:

Guitar.txt

Guitar ESP-LTD 6-String Electric Guitar 300 1 

Candy_Bar.txt

Candy Bar Twix Chocolate Bar 1 4 

Shoes.txt

Shoes Classic Black Converse 50 2 

Let me explain what you are seeing in each text file. The first line contains the name of the product, the next line is the description of that product, the next line is the items price in dollars, the last line is the quantity of that product. Each time the user chooses to add one of these items to the menu, your task will be to successfully add the correct information to the ShoppingCart. Each time you add one of these items I would like for you to output either:

ADDED GUITAR TO CART 

or

ADDED CANDY BAR TO CART 

or

ADDED SHOES TO CART 

In correlation with whatever item was added.

(7) Implement Output shopping cart menu option. Ex:

OUTPUT SHOPPING CART John Doe's Shopping Cart - September 19, 2018 Number of Items: 7 Guitar 1 @ $300 = $300 Candy Bar 4 @ $1 = $4 Shoes 2 @ $50 = $100 Total: $404 

(8) Implement Output item's description menu option. Ex.

OUTPUT ITEMS' DESCRIPTIONS John Doe's Shopping Cart - September 19, 2018 Item Descriptions Guitar: ESP-LTD 6-String Electric Guitar Candy Bar: Twix Chocolate Bar Shoes: Classic Black Converse 

(8) Implement Remove item menu option. Ex:

REMOVE ITEM FROM CART Enter name of item to remove: Candy Bar 

(9) Implement Change item quantity menu option. Hint: Make new ItemToPurchase object and use ItemToPurchase modifiers before using modifyItem() method. Ex:

CHANGE ITEM QUANTITY Enter the item name: Shoes Enter the new quantity: 3
