ecorator Design Pattern Explained | LLD | Get SDE Ready | System Design Interview

In this video, we explore the Decorator Design Pattern in Java, demonstrating how it helps in building a dynamic car pricing feature while avoiding class explosion. Learn how wrapping functionalities dynamically makes your code more flexible and scalable.

Highlights:
🔹 Understanding Decorator Pattern – Enhancing object behavior dynamically.
🔹 Car Pricing Implementation – Adding features without modifying the base class.
🔹 Avoiding Class Explosion – Using decorators instead of multiple subclasses.
🔹 Flexibility & Maintainability – Making software development more adaptable.
🔹 Real-World Use Cases – Where and when to apply the pattern.

Key Insights:
✔️ Dynamic Feature Addition – Modify behavior at runtime without altering the original class.
✔️ Scalable Software Design – Reduce subclass dependencies and improve code maintainability.
✔️ Code Reusability – Implement new functionalities without redundant code.
✔️ Object-Oriented Programming Best Practices – Leveraging composition over inheritance.
