Cyber Management System in Java - CLI Auth Handler & AuthService (Part 2)

In this video, I will guide you through building a Cyber Management System in Java using Object-Oriented Programming (OOP) with a Command Line Interface (CLI) and JSON file storage using Gson in Eclipse IDE (2025). This project simulates a real-world cybercafé management system, where admins can add or remove terminals, handle client sessions, and generate detailed reports.

By following this tutorial, you will learn how to:
✔️ Design a modular, OOP-based cyber management system in Java
✔️ Build a fully functional CLI interface for admins and clients
✔️ Implement authentication (login/logout) and session handling
✔️ Manage different types of terminals and their statuses
✔️ Save and load data using JSON with Gson (including custom adapters)
✔️ Generate daily reports and client usage histories

This project is perfect for Java learners aiming to apply OOP principles in a real-world café management scenario.
