This is a simple Java-based console application that simulates a basic e-commerce shopping cart system. It allows users to select products, choose a shipping method, and complete payment through a text-based interface.
- Products are predefined with unique IDs, names, prices, weights, and stock quantities.
- Users can add products to the shopping basket by entering the product ID and quantity.
- Users can choose between Standard Shipment, Express Shipment, and Special Shipment.
- Shipping costs are calculated based on total weight using different multipliers.
- Two payment methods are available:
- Credit Card Payment: Enter card number to process payment.
- EFT/Transfer Payment: Enter IBAN number to complete payment.
- The total cost includes the basket total and shipping cost.
- Java
- Object-Oriented Programming concepts:
abstract classes,interfaces, andinheritance
-
Compile the Code
Make sure you have JDK installed. Use the following command to compile:javac Main.java
-
Run the Program
Execute the program using:java Main
-
Follow the Instructions
- Enter product IDs and quantities to add items to the cart.
- Choose a shipping method.
- Choose a payment method to complete the purchase.
Enter the product ID and quantity to add to the cart (example: ID55268, ID55287):
Please enter the product ID (Press Q to quit): ID55268
Enter the quantity: 2
Please enter the product ID (Press Q to quit): ID55287
Enter the quantity: 1
Please enter the product ID (Press Q to quit): Q
Your Shopping Basket:
Product: Laptop
Quantity: 2
Unit Price: $1000.00
Total Price: $2000.00
Product: Phone
Quantity: 1
Unit Price: $100.00
Total Price: $100.00
Represents a product with:
id: Unique product ID.name: Product name.price: Product price.stock: Available stock quantity.weight: For calculating shipping cost.
Handles:
- Adding products to the basket.
- Calculating the total price of items.
Base class for payment methods. Derived classes:
CreditCardPayment: Handles payments via credit card.EFTPayment: Handles payments via EFT/Transfer.
Defines a method for calculating shipping costs. Implementations:
StandardShipment: Shipping cost = weight × 1.0ExpressShipment: Shipping cost = weight × 1.5- **
SpecialShipment: Shipping cost = weight × 2.0
- Add more products dynamically from the user.
- Implement persistent storage for products and transactions.
- Add user authentication for secure payments.
This was a collaborative project, and my personal contributions included:
- Designing and implementing the
Productclass structure. - Developing the abstract
Paymentsystem and its subclasses (CreditCardPayment,EFTPayment). - Creating the
Main.javafile, which handles program execution and user interaction flow.
