Bottled Water 10 @ $1 = $10Ex. of printItemDescription() output:Bottled Water: Deer Park, 12 oz.2. Create two new files ShoppingCart.java - Class definition ShoppingCartManager.java - Contains main() methodBuild 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, 2020" ArrayList cartItems where each item is of type ItemToPurchase Coupon code - Enum class with constants 10OFF, 20OFF, 30OFFPublic member methods Default constructor Parameterized constructor which takes the customer name and date as parameterso getCustomerName() accessoro getDate() accessor addItem() Adds an item to cartItems array. Has parameter ItemToPurchase. Does not return anythingremoveItem()o Removes item from cartItems array. Has a string (an item's name) parameter. Does not return anythingo If item name cannot be found, output this message: Item not found in cart. Nothing removed. modifyItem()o Modifies an item's description, price, and/or quantity. Has parameter Bottled Water 10 @ $1 = $10Ex. of printItemDescription() output:Bottled Water: Deer Park, 12 oz.2.

Has parameter

ItemToPurchase. Does not return anything.o 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.o If item cannot be found (by name) in cart, output this message: Item not found in cart. Nothing modified. getNumItemsInCart() o Returns quantity of all items in cart. Has no parameters. getCostOfCart() o Determines and returns the total cost of items in cart. Has no parameters.applyCouponCode() A coupon code can be applied based on the following conditions: 10OFF - $10 off the total price if current total exceeds $50 20OFF - $20 off the total price if current total exceeds $100 30OFF - $20 off the total price if current total exceeds $150 printTotal()o outputs total of objects in cart. Apply any applicable coupon codes.o If invalid coupon code is applied, output the message: INVALID CODEo If cart is empty, output this message: SHOPPING CART IS EMPTYExample of PrintTotal()output:John Doe's Shopping Cart - February 1, 2020 Number of Items: 8Nike Romaleos 2 @$189 = $378 Chocolate Chips 5 @ $3 = $15Powerbeats 2 Headphones 1 @ $128 = $128Discount (30OFF): -$30 Total: $491 printDescription()o Outputs each items description. Example of printDescription()output:John Doe's Shopping Cart - February 1, 2020Item Descriptions

3. In the file ShoppingCartManager.java, have the main method prompt the user for a customer's name and today's date. o Output the name and date.o Create an object of type ShoppingCart. Output Example:Enter Customer's Name: John DoeEnter Today's Date:February 1, 2020Customer Name: John Doe Today's Date: February 1, 20204. Implement the printMenu() method in ShoppingCartManager.java. 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 methodo If there is an invalid character is entered, continue to prompt for a valid choice. Hint: Implement Quit before implementing other options. o Call printMenu() in the main() method. o Continue to execute the menu until the user enters q to Quit.Output Example:MENUa - Add item to cartd - Remove item from cart c - Change item quantityi - Output items' descriptions o - Output shopping cartp - Apply coupon codeq - QuitChoose an option:5. Implement Output shopping cart menu optionOutput Example:OUTPUT SHOPPING CARTJohn Doe's Shopping Cart - February 1, 2020 Number of Items: 8 Nike Romaleos 2 @ $189 = $378 Chocolate Chips 5 @ $3 = $15 Powerbeats 2 Headphones 1 @ $128 = $128Discount (30OFF): -$30 Total: $491
