## Overview

This is an in-memory, console-based university student management system. The principal workflow starts with a console user choosing an operation in `Main`: student records are registered or searched and sorted through `StudentService`, grades and semester fees are calculated, and record and department-fee reports are displayed. Faculty records support the university-directory polymorphism demonstration. The model defines student/person and payable/reporting contracts; there is no persistent database or external service. The README documents the evaluator demonstrations, but their individual control flow is not fully sampled.
