POS Application Project

Project Overview

This project is a Point of Sale (POS) application designed to manage sales transactions, inventory, products, payments, customers, reports, and employees. The application follows object-oriented principles to ensure a modular and maintainable codebase.

Project Structure

The project consists of the following key components:

SalesTransaction: Manages sales transactions, calculates totals, applies discounts, and generates receipts.
Inventory: Tracks inventory, receives shipments, and updates stock levels.
Product: Represents products in the inventory, with attributes such as product ID, name, description, price, category, and stock level.
Payment: Processes payments, verifies payments, and generates payment receipts.
Customer: Manages customer information, purchase history, and loyalty points.
Report: Generates, exports, and displays reports based on sales data.
Employee: Tracks employee hours, manages permissions, and generates payroll information.
SystemSettings: Manages system settings, user preferences, and security settings.

Usage

The Main class contains a sample implementation to demonstrate the basic functionality of the POS application.
You can create, manage, and display products, sales transactions, customers, inventory, and more.

Example

Here is an example of how to create and use some of the classes:

public class Main {
    public static void main(String[] args) {
        // Create some products
        Product product1 = new Product("P001", "Apple", 0.50);
        Product product2 = new Product("P002", "Banana", 0.30);

        // Create a sales transaction
        SalesTransaction transaction = new SalesTransaction("T001", "2024-07-19");
        transaction.addItem(product1);
        transaction.addItem(product2);

        // Calculate total and generate receipt
        transaction.calculateTotal();
        System.out.println(transaction.generateReceipt());

        // Create a customer
        Customer customer = new Customer("C001", "John Doe");
        customer.addPurchaseHistory(transaction);

        // Create an inventory and add products
        Inventory inventory = new Inventory("I001");
        inventory.receiveShipment(product1);
        inventory.receiveShipment(product2);

        // Display product info
        product1.displayProductInfo();
        product2.displayProductInfo();
    }
}
