🎓 College Course Registration System

A Core Java console-based application that simulates a college course registration system. The project demonstrates Object-Oriented Programming (OOP) principles and Core Java concepts including Inheritance, Polymorphism, Collections Framework, and Exception Handling.

This project was developed as an MCA Core Java Termwork.

🧩 Java Concepts Implemented

Inheritance

Person
├── Student
└── Admin

Student and Admin classes inherit common properties from the Person class.

Polymorphism

Person p1 = currentStudent;
p1.dashboard();

Person p2 = admin;
p2.dashboard();

Method overriding is used to provide different dashboard implementations for Student and Admin.

Collections Framework

The project uses:

ArrayList<Course>
HashMap<Integer, Student>
Iterator<Course>

• ArrayList for course storage
• HashMap for student management
• Iterator for safe removal operations

Exception Handling

Custom Exceptions:

CourseFullException
AlreadyRegisteredException
CourseLimitExceededException

Built-in Exception:

InputMismatchException
