Chain of Responsibility pattern is used to decouple the request and response handling. Multiple objects create a chain that is used to handle a request. This article demonstrates Chain of Responsibility pattern implementations in Java. Check the following examples.
Chain of Responsibility pattern forms a chain of objects that is responsible for handling a command/operation request. As the responsibility is distributed into one or more objects and a single object is not responsible for handling a request, so that ensures the decoupling of the request sender and processor. The request is sent to the chain of objects without specifying the handler. Which object will handle the request is not predefined, that is decided on-the-fly while processing.
