Create an Item class that models an Item to be purchased. It should contain instance data and a constructor to hold the following characteristics: name, price and quantity. Item class should also include accessor methods for the 3 characteristics and a toString summary.
Create a Cart class that is responsible for managing items. ShopApp should only manipulate the contents of the cart by calling methods on Cart. It should not talk directly to Item instances.
Build out methods that ...
- add items to the cart
- Stretch task remove items from the cart
- display the contents of the cart
- display the current order in the cart
- Stretch task give the ability to change a particular quantity of an order
Create an ArrayList to hold Item instances. Call your ArrayList items. Here is an example of an ArrayList declaration that holds String instances:
ArrayList<String> ingredients = new ArrayList<String>();The ShopApp class should be designed to model shopping in similar fashion to Amazon and other online sites (where you can add to cart and you will see your total increase with each item added). Use a loop to simulate shopping, asking the user to enter the item, quantity and price. (You will need variables for these.) Store the items in an ArrayList and update the total due at checkout.
Stretch task: Provide an opportunity to remove an item from the shopping cart if a user no longer desires to make that particular purchase.
