In this video, we dive deep into the Observer Design Pattern—one of the most important behavioral design patterns in software development. You'll learn how to establish a one-to-many dependency between objects, allowing a subject to notify its observers automatically whenever its state changes.
🔹 What you'll learn:
- The core components of the Observer Design Pattern (Subject, Observer, Concrete Subject, Concrete Observer)
- How to implement the pattern in Java
- A real-world example using a stock price tracker and user notifications
- When and why you should use the Observer Pattern in your software
📘 Example code: We’ll walk through step-by-step Java code to show how to implement this pattern, and how it keeps your codebase flexible and decoupled.
👩💻 Whether you’re preparing for interviews or building scalable software, mastering the Observer Design Pattern is essential!
