I want to make a new method in Shoppingcart.java that gives discount as mentioned in the following screenshot:-

and mentain trend between ShopingCart and ShopingCartManager

stain viruses. Unless you need to edit, it's safer to stay in Protected View. Enable Editing Enter name of item to remove: Chocolate Chips 9. Implement Change item quantity menu option. Output Example: CHANGE ITEM QUANTITY Enter the item name: Nike Romaleos Enter the new quantity: 3 10. Implement the Apply coupon code menu option. When an invalid coupon code or a coupon code which doesn't meet the condition is applied, it should be rejected with the message "INVALID CODE'. Else, display the message 'COUPON APPLIED'. Output Example: APPLY COUPON CODE Enter coupon code: 200FF INVALID CODE Enter coupon code: 100FF COUPON APPLIED Hint: Make new ItemToPurchase object and use ItemToPurchase modifiers before using modifyItem( uantity. If not, modify item in cart. o If item cannot be found (by name) in cart, output this message: Item not fc cart. Nothing modified getNumItemsInCart() 0 Returns quantity of all items in cart. Has no parameters. getCostOfCarto O Determines and returns the total cost of items in cart. Has no parameters. applyCoupon Code A coupon code can be applied based on the following conditions: 100FF - $10 off the total price if current total exceeds $50 200FF - $20 off the total price if current total exceeds $100 300FF - $20 off the total price if current total exceeds $150 . O O O print Total outputs total of objects in cart. Apply any applicable coupon codes. If invalid coupon code is applied, output the message: INVALID CODE O
