Demonstrate the following:

Usage of Eclipse Variable Assignment Looping (for, while etc) ArrayList (using object) Object based programming User Interaction with multiple options Implementing Methods in relevant classes Instructions

Start with this java classes Item.java, ShoppingCart.java, and ShoppingCartTester.java

You will model ShoppingCart as java Class.

ShoppingCart class will store Items in the cart. Item will be another java class. Item is identified by Id attribute. If the Item with the same Id is added multiple times in the cart, change the quantity and DO NOT add multiple Item objects with same Id.

The program should prompt various actions on ShoppingCart addItemToCart Two overloads updateItemQuantity removeItemFromCart calculateItemBasedDiscount getTotalCost

Implement discount based on total quantity of items

- If total number of quantity ACROSS ALL Items is less than 11 , apply LOW_DISCOUNT (10% discount)

- If total number of quantity ACROSS ALL Items is more than 10 but less than 26, apply MEDIUM_DISCOUNT (25% discount)

- If total number of quantity ACROSS ALL Items is more than 26, apply HIGH_DISCOUNT (50% discount)return discount; }

Based on the selected action ask for further input. For example, if user selects to addItemToCart, prompt user to enter itemId itemName itemPrice itemQuantity

Implement all methods in ShoppingCart.java

Write test in ShoppingCartTester.java. Use scanner to implement userInputSimulator() method. See sample output for sample run. Before you start working on user input, implement the tester methods as provided in the starter code. Once you have everything working enable the user input and comment out the tester code. Gracefully exit the program
