Java Behavioral pattern Chain of Responsibility Design Pattern with code

In this video we explore the Chain of Responsibility Design Pattern in Java, one of the classic Behavioral design patterns described in the Gang of Four book. The Chain of Responsibility pattern allows a request to pass through a chain of handler objects. Each handler decides whether it can process the request or pass it to the next handler in the chain. This approach decouples the sender of a request from the object that ultimately handles it, making systems easier to extend and maintain. README In this example, we demonstrate the pattern using a fun sandwich-making scenario where each handler is responsible for adding a specific ingredient. If the handler cannot process the request, it passes it along to the next handler in the chain.
