🔌 Adapter Design Pattern Explained | Real-Life Analogy + Code Examples

Ever wanted two incompatible interfaces to work together? That’s exactly what the Adapter Pattern is for!

In this video, you’ll learn how the Adapter Design Pattern helps you connect mismatched interfaces using real-world analogies (like charging adapters!) and clear code demos.

🎯 What You’ll Learn:
✅ What is the Adapter Pattern?
✅ Real-life analogies that make it easy to remember
✅ How to implement it in code (Class Adapter vs Object Adapter)
✅ When to use it and common pitfalls to avoid

💡 Part of the Structural Design Patterns, the Adapter is perfect when:

You want to integrate legacy code with modern systems

You need to work with incompatible APIs

You're preparing for coding interviews or system design questions

👨‍💻 Great for:

Software Developers

Interview Prep (especially for FAANG roles)

Students learning OOP & Design Patterns

🔒 Singleton Design Pattern Explained | Real-World Examples & Use Cases

Struggling to understand the Singleton Pattern? In this video, we’ll break it down step-by-step with real-world examples and easy-to-follow code!

🎯 What You'll Learn:
✅ What is the Singleton Design Pattern?
✅ When and why to use it
✅ Real-world analogies to simplify understanding
✅ Thread-safe implementation tips (Lazy, Eager, Double-Checked Locking)
✅ Common mistakes to avoid

💡 The Singleton Pattern ensures a class has only one instance and provides a global point of access to it. It’s widely used in logging, configuration management, driver objects, and more!

👨‍💻 Ideal for:

Beginners learning design patterns

Interview prep (especially for FAANG!)

Developers writing scalable and maintainable code
