Shopping Cart Project

This is a Java-based project that simulates a shopping cart system. The project demonstrates object-oriented programming concepts, including the use of classes, constructors, arrays, and methods. It also incorporates basic error handling and array operations.

Project Description

The project consists of the following components:

1. Product Class:

   • Represents a product with attributes: id, description, price, and quantity.
   • Includes a constructor to initialize the attributes.
   • Provides a method displayProductInfo() to display product details.

2. ShoppingCart Class:

   • Manages a collection of products using an array with a fixed size of 5.
   • Includes methods to:
     • Add a product to the cart (addProductToCart(Product product)), ensuring valid input.
     • Calculate the total cost of products in the cart (calculateTotalCost()).
     • Display the contents of the cart (displayCartContents()).

3. Main Class:

   • Demonstrates the functionality of the Product and ShoppingCart classes.
   • Instantiates three products and adds them to the shopping cart.
   • Displays the cart contents and calculates the total cost.

Features

• Add products to the shopping cart.
• Validate product price before adding.
• Display product details and cart contents.
• Calculate and display the total cost of the products in the cart.
• Handles scenarios like full cart and empty cart.
