Adapter Design Pattern in Java Explained - How to Handle 3rd Party APIs & Legacy Code (UML + Code)

Описание: The Adapter Design Pattern is a structural design pattern that helps you integrate incompatible interfaces by acting as a bridge between two systems.

In this video, you will learn:

✅ What is Adapter Design Pattern and why it’s essential
✅ Problems faced when integrating with 3rd party APIs without Adapter (like Stripe or Razorpay)
✅ How Adapter Pattern simplifies working with 3rd party payment gateways by wrapping their APIs into your own interface
✅ How Adapter helps to deal with legacy code without changing its core logic
✅ UML diagram explaining the pattern’s structure
✅ Clean Java code example demonstrating Adapter in action with payment APIs
This pattern is a must-know for Java developers working with external APIs or maintaining legacy systems.
