# E-commerce System
## Project Overview
This is a Java-based e-commerce system that simulates online shopping functionality. The system handles product management, shopping cart operations, customer checkout, and shipping services. It demonstrates object-oriented programming principles with a clean separation of concerns across different packages.
## Features
- **Product Management**: Support for different product types (Expirable/non-Expirable, shippable/non-shippable)
- **Shopping Cart**: Add items to cart with quantity validation
- **Customer Management**: Customer balance tracking and transaction processing
- **Checkout System**: Complete checkout process with receipt generation
- **Shipping Service**: Automated shipping calculations and shipment notices for shippable items
- **Error Handling**: Comprehensive validation for stock, expiration, and balance checks
## Project Structure
```

│── cart/
│ ├── Cart.java # Shopping cart management
│ └── CartItem.java # Individual cart item representation
├── customer/
│ └── Customer.java # Customer entity and checkout logic
├── main/
│ └── Main.java # Entry point with test cases
├── product/

```
## How to Run
### Prerequisites
- Java Development Kit (JDK) 8 or higher
- Command line interface (Terminal/Command Prompt)
### Compilation and Execution
