    Problem Statement:
    You are required to write a Java program, named ShoppingCart, for a typical online shopping system. In which a user can add and remove items to the shopping cart. The program will allow the user to proceed with checkout by displaying all items of the shopping cart along with total bill. Further, user will also be fascinated by giving the option of emptying the shopping cart without buying anything. All will be done by using Java basic GUI component i.e. JOptionPane.

    Detailed Description:
    At start, your program should display an Input Dialog (i.e. JOptionPane.showInputDialog) and ask for following options;

    1. Add Item(s) to Cart

    2. Remove an Item from Cart

    3. Go to Checkout

    4. Empty the Cart

    5. Exit the Program
      Fig. 1: Shopping Cart GUI

    6. Add Item(s) to Cart:

    Each time, user selects this option, s/he will be prompted via two Input Dialogs (i.e. JOptionPane.showInputDialog) for selecting an item from available items list (sample data is given below) and its quantity respectively. If inputs are correct (i.e. found no empty/null value and quantity is between 1 and 10) then selected item and its quantity will be added in the shopping cart by using ArrayList from java.util.* package.

    Fig. 2: Adding items in Shopping Cart

    1. Remove an Item from Cart:

    User can remove any item from the shopping cart by using this option; JOptionPane.showInputDialog should be used here. However, if shopping cart is already empty then message “Cart is empty” via JOptionPane.showMessageDialog should be displayed.

    Fig. 3: Remove an Item

    1. Go to Checkout:

    The program should first check if shopping cart contains any item; if not, it means no item is added yet so ask user to add a new item first. Otherwise, a Message Dialog (i.e. JOptionPane.showMessageDialog) will be opened, displaying all added items along with their quantity and prices. Furthermore, total number of items and grand total should be provided at bottom as well.

    4. Empty the Cart:

    User can remove all items from the shopping cart at once by using this option; successful deletion message should be displayed by using JOptionPane.showMessageDialog. However, if shopping cart is already empty then appropriate message like "Cart is empty" should be displayed.

    5. Exit the Program:

    Exit option will terminate the program and show the developer information (i.e. Student Id and name) via JOptionPane.showMessageDialog.

    Required Java Classes:
    For this purpose, you have to create three java classes (i.e. Product, Cart and MainClass). Data members, member functions and other details of these classes are given below;

    Product Class:

    •	id: int
    •	name: String
    •	price: float
    •	quantity: int
    •	Constructors: default, parameterized and copy constructor
    •	Standard Setters: setId(…), setName(…), setPrice(…), setQuantity(…)
    •	Standard Getters getId(), getName(), getPrice(), getQuantity()

    Cart Class:

    Cart Class:
    •	cartItems: ArrayList 
    •	Constructors: default, parameterized and copy constructor
    •	Member Functions: addItem(…), removeItem(…), emptyCart(), getItemsList(), getProductIndex(…)

    Main Class:

    •	myCart: Cart
    •	Constructors: default, parameterized and copy constructor
    •	Member Functions: main(), showGUI(), addItem(), removeItem(), checkOutCart(), removeAll(), developerInfo()

    Sample Data:

    Important Things to Implement:

    • For GUI, you have to use JOptionPane.showInputDialog and JOptionPane.showMessageDialog for taking input from user and showing output to user respectively.
    • Use single ArrayList for adding/removing items to/from shopping cart.
    • Need to make sure that exceptions are managed properly throughout the program; especially NullPointerException and NumberFormatException while taking input from user.
    • All images and sample data, given in this document, are just for reference purpose only; you have to provide your own implementations. It is not required to be exactly the same.

    Good Luck
