Chain of Responsibility Design Pattern: → Avoid coupling the sender of a request to its receiver by giving more than one receiver object a chance to handle the request. → Chain the receiving objects and pass the request along the chain until an object handles it. → It creates a chain of receiver objects for a request. → Each receiver contains reference to another receiver. If one receiver cannot handle the request then it will pass to the next receiver. → (One receiver handles a request in the chain) or (One or more receivers in the chain handles a request). ------------------------------
