CS506 Assignment 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 the start, your program should display an Input Dialog (i.e. JOptionPane.showInputDialog) and ask for the following options;

Add Item(s) to Cart

Remove an Item from Cart

Go to Checkout

Empty the Cart

Exit the Program

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:

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()

Important Things to Implement:

For GUI, you have to use JOptionPane.showInputDialog and JOptionPane.showMessageDialog for taking input from the user and showing output to users respectively.
Use single ArrayList for adding/removing items to/from the shopping cart.
We need to make sure that exceptions are managed properly throughout the program; especially NullPointerException and NumberFormatException while taking input from the 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.
