Student Management System

Overview

This project is a Java-based Student Management System developed to demonstrate:

• Builder Design Pattern
• Inheritance and Polymorphism
• Application of SOLID Principles
• Clean, modular, and extensible code design

The system supports different types of students:

• Undergraduate Student
• Graduate Student

Each student type extends the abstract base class Student.

Design Patterns Used

1. Builder Pattern

The Builder Pattern is implemented in:

• UndergraduateStudent.Builder
• GraduateStudent.Builder

Because students have required and optional attributes, the Builder Pattern:

• Simplifies object creation
• Improves readability
• Avoids constructor overloading
• Allows optional attributes to be set fluently

Example (from Main.java):

UndergraduateStudent undergrad =
        new UndergraduateStudent.Builder(
                "U123",
                "Liyabona Dyantyi",
                "liyabona@email.com",
                "Computer Science")
                .creditHours(6)
                .scholarshipAmount(1000)
                .build();
