Please Create a new code for java:

Please do not copy and paste a code from a previously answered question unless you modify it to satify the given tests at the end because they are not adequate enough to satisfy anything otherwise I feel my question is wasted.

21.17 Ch 7 Program: Online shopping cart (Java)

Note: Creating multiple Scanner objects for the same input stream yields unexpected behavior. Thus, good practice is to use a single Scanner object for reading input from System.in. That Scanner object can be passed as an argument to any methods that read input. 3

(1) Create a class called ItemToPurchase.java 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). (1 pt)

* Public member methods

* setDescription() mutator & getDescription() accessor (2 pts)

* 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, 2016"

* ArrayList cartItems

* Default constructor

* Parameterized constructor which takes the customer name and date as parameters (1 pt)

* Public member methods

* getCustomerName() accessor (1 pt)

* getDate() accessor (1 pt)

* 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() (2 pts)

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

* getCostOfCart() (2 pts)

- 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 - February 1, 2016 Number of Items: 8 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 - February 1, 2016 Item Descriptions Nike Romaleos: Volt color, Weightlifting shoes Chocolate Chips: Semi-sweet Powerbeats 2 Headphones: Bluetooth headphones

(3) In main(), prompt the user for a customer's name and today's date. Output the name and date. Create an object of type ShoppingCart. (1 pt)

Ex.

Enter Customer's Name: John Doe Enter Today's Date: February 1, 2016 Customer Name: John Doe Today's Date: February 1, 2016

(4) 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 within the method.

If the 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. (3 pts)

Ex:

MENU a - Add item to cart d - Remove item from cart c - Change item quantity i - Output items' descriptions o - Output shopping cart q - Quit Choose an option:

(5) Implement Output shopping cart menu option. (3 pts)

Ex:

OUTPUT SHOPPING CART John Doe's Shopping Cart - February 1, 2016 Number of Items: 8 Nike Romaleos 2 @ $189 = $378 Chocolate Chips 5 @ $3 = $15 Powerbeats 2 Headphones 1 @ $128 = $128 Total: $521

(6) Implement Output item's description menu option. (2 pts)

Ex.

OUTPUT ITEMS' DESCRIPTIONS John Doe's Shopping Cart - February 1, 2016 Item Descriptions Nike Romaleos: Volt color, Weightlifting shoes Chocolate Chips: Semi-sweet Powerbeats 2 Headphones: Bluetooth headphones

(7) Implement Add item to cart menu option. (3 pts)

Ex:

ADD ITEM TO CART Enter the item name: Nike Romaleos Enter the item description: Volt color, Weightlifting shoes Enter the item price: 189 Enter the item quantity: 2

(8) Implement Remove item menu option. (4 pts)

Ex:

REMOVE ITEM FROM CART Enter name of item to remove: Chocolate Chips

(9) Implement Change item quantity menu option. Hint: Make new ItemToPurchase object and use ItemToPurchase modifiers before using modifyItem() method. (5 pts)

Ex:

CHANGE ITEM QUANTITY Enter the item name: Nike Romaleos Enter the new quantity: 3
