In this video, we deep dive into the Iterator Design Pattern — one of the most practical and underrated patterns in object-oriented design!
💬 Through a real-world example of a music playlist feature (linear and random playback), we’ll:
🎯 Understand why the Iterator pattern was introduced
🧩 Do a bit of reverse engineering to derive it ourselves
⚙️ Explore how it solves SOLID principle violations (especially Open/Closed and Single Responsibility)
🧠 See what issues occur without using the pattern
💻 Finally, implement the complete Iterator Pattern in Java
Whether you’re preparing for design pattern interviews or working on scalable backend features, this video will help you understand Iterator Pattern deeply and practically.
👉 Watch till the end — the explanation connects design principles with real code logic!
