A Desktop E-Supermarket Application

E-Supermarket is a fully functional desktop application developed as part of a university project by Nicholas Christoforou(me) and Leandros Kelpis. This application is designed for managing and shopping in a supermarket e-shop environment. It allows both administrators and customers to interact with the system, manage products, place orders, and view order history. With separate functionalities for administrators and customers, E-Supermarket ensures smooth operation for both user types. The app is built in Java, following object-oriented programming principles, and incorporates file-based storage for persistence.
