Understanding the Adapter Design Pattern in Java
The Adapter Design Pattern is a structural design pattern that allows objects with incompatible interfaces to work together. It acts as a bridge, converting the interface of a class into another interface clients expect, enabling collaboration despite incompatibility. In this post, we will explore the Adapter Pattern with practical real-world examples, including how it helps adapt different data formats or object interfaces. What is the Adapter Design Pattern? Adapter Pattern allows wrapping an incompatible object with an adapter so that it matches the expected interface. This is commonly used when integrating third-party libraries, legacy code, or systems with varying data formats. Real-World Example: Swiggy Food & Grocery Delivery Imagine the Swiggy app initially supports only food items from restaurants. With the pandemic, it needs to support grocery items from stores, which have a different interface. Using the Adapter Pattern, grocery items are adapted to the existi...
