Interactive Demo
OOP Memory Visualizer
OOP Memory Visualizer is a free, interactive learning demo from the Java Programming and Algorithmic Thinking Fundamentals course on Lykke. It helps you build intuition for Classes and Objects, Constructors and Overloading, Encapsulation (Private vs. Public), Static vs. Instance Variables. Play with it directly in your browser — it features 1 button and direct drag interaction. This demo lives in the “Object-Oriented Programming (OOP)” section of the course.
How to use this demo
- Click and drag directly on the canvas to manipulate the scene.
- Use the “Clear RAM” button to trigger actions or reset the demo.
- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- Classes and Objects
- Constructors and Overloading
- Encapsulation (Private vs. Public)
- Static vs. Instance Variables
- Method Overriding (toString, equals)
Frequently asked questions
What does the OOP Memory Visualizer demo do?
Designing custom data types using classes, encapsulation, and object-oriented principles. OOP Memory Visualizer turns that idea into something you can manipulate directly and watch respond.
What Java Programming and Algorithmic Thinking Fundamentals concept does OOP Memory Visualizer teach?
Designing custom data types using classes, encapsulation, and object-oriented principles. It focuses on Classes and Objects, Constructors and Overloading, Encapsulation (Private vs. Public), Static vs. Instance Variables, Method Overriding (toString, equals) from the “Object-Oriented Programming (OOP)” section.
What can I control in OOP Memory Visualizer?
You can drag elements directly on the canvas; the “Clear RAM” button run actions or reset the demo. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.
How does OOP Memory Visualizer fit into the Java Programming and Algorithmic Thinking Fundamentals course?
This course provides a comprehensive introduction to computer science using the Java programming language. It covers fundamental concepts ranging from basic syntax and control flow to complex topics like recursion, obje… This demo is the interactive piece for the “Object-Oriented Programming (OOP)” section.

What will I understand better after using OOP Memory Visualizer?
You'll build intuition for Classes and Objects, Constructors and Overloading, Encapsulation (Private vs. Public), Static vs. Instance Variables, Method Overriding (toString, equals) — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on Java Programming and Algorithmic Thinking Fundamentals alone.
