## Overview

Food-Delivery-Management is a Java Swing application for administering a food menu, placing orders, and handling employee notifications. Users enter through login/sign-up and are routed by role; clients browse/search and submit orders, administrators manage products and generate reports, and employees observe new orders. DeliveryService coordinates business operations, while file helpers and serialization persist data and produce bills/reports. The README documents several capabilities whose detailed implementation was not sampled; those links are shown as documented rather than inferred from unsampled calls.

Main entry points: [`src/main/java/business/DeliveryService.java`](https://github.com/jurcandiana/food-delivery-management/blob/main/src/main/java/business/DeliveryService.java) (Delivery service), [`src/main/java/presentation/LogInGUI.java`](https://github.com/jurcandiana/food-delivery-management/blob/main/src/main/java/presentation/LogInGUI.java) (Login and signup), [`src/main/java/presentation/AdministratorGUI.java`](https://github.com/jurcandiana/food-delivery-management/blob/main/src/main/java/presentation/AdministratorGUI.java) (Administrator UI), [`src/main/java/presentation/ClientGUI.java`](https://github.com/jurcandiana/food-delivery-management/blob/main/src/main/java/presentation/ClientGUI.java) (Client UI)
