Object-Oriented Programming Project

This project demonstrates fundamental object-oriented programming principles in Java. It involves creating three classes: Person, Student, and Staff. The Person class serves as a base class, with Student and Staff inheriting from it. Each class has its own attributes and methods, showcasing encapsulation. The Student class includes attributes like program, year, and fee, while the Staff class includes school and pay. A test class instantiates objects of these classes and demonstrates the use of methods, including the toString() method for output. The provided code includes the complete Java source code for each class, along with a test class to demonstrate functionality. The output section shows the expected console output when running the test class.
