Java Student Tracker

Overview

This project is a menu-driven Java console program that simulates a simple University Student Database.

It demonstrates key OOP concepts:

• Classes & Objects
• Inheritance
• Aggregation
• Array of Objects / ArrayList

The system allows the user to manage both Undergraduate and Graduate students, store their data, and check their graduation eligibility.
