Participants typically include a Handler interface with a method to set the next handler and a method
Behaviorwise, the request enters the chain and is passed from handler to handler. A handler that can
Advantages include decoupling of sender and receiver, improved maintainability, and the ability to configure processing steps
Common use cases are middleware pipelines in web frameworks, event handling in GUI systems, and error or
