We can understand that the responsibility chain mode is a chain composed of processing requests. Requests are passed between these objects in turn until we encounter an object that can process it. We call these objects nodes in the chain. For example, object a sends a request to object b. If object b does not process, it will give the request to c. If object c does not process, it will give the request to d, and so on, until one object can process the request. Of course, if no object processes the request, then the request will leave the chain.
Each object has its corresponding state, and each state corresponds to some corresponding behaviors. If an object has multiple states, there will be many behaviors. Then the judgment of these states and the behavior completed according to the states will lead to multiple conditional statements, and if a new state is added, the existing code needs to be changed. This kind of design obviously violates the principle of opening and closing, and the state mode is used to solve such problems.
