Java Programming Live Coding Session 2026 | Classes, Objects, Polymorphism & Constructors
Welcome to this Java Programming Live Coding Session 🎯 — designed especially for beginners and students who want to strengthen their understanding of Object-Oriented Programming (OOP) concepts in Java through practical coding exercises and real exam-style questions.
In this interactive session, we’ll write and test Java programs live, explain each concept step-by-step, and demonstrate how OOP principles such as inheritance, constructors, and polymorphism are applied in real-world systems.
💻 What You’ll Learn:
✅ Understanding Constructors in Java
✅ Difference between No-Argument and Parameterized Constructors
✅ Creating and Using Classes and Objects
✅ Implementing Inheritance in Java
✅ Applying Runtime Polymorphism
✅ Overriding Methods in Subclasses
✅ Designing Simple Real-World Java Systems
🧑🏽💻 Java OOP Questions We’ll Solve Live:
1️⃣ Understand constructors in Java and distinguish between no-argument and parameterized constructors with examples.
2️⃣ Build a College Assessment System using:
Module class
Learner class
DiplomaStudent subclass
DegreeStudent subclass
Runtime polymorphism
3️⃣ Design a University Grading System using:
Course class
Student class
UndergraduateStudent subclass
GraduateStudent subclass
Polymorphism through overridden methods
