If we have to change the behavior of an object based on its state, we can have a state variable in the Object. Then useif-elsecondition block to perform different actions based on the state. State design pattern

State Design Pattern State pattern is one ofthe behavioral design pattern. State design pattern is used when an Object changes its behavior based on its internal state. If we have to change behavior of an object based on its state, we can have a state variable in the Object and use if-e...

In state design pattern, a state allows an object to alter its behavior when its internal state changes. The object will appear to change its class.

设计模式-状态模式(State Pattern) 推荐:Java设计模式汇总 状态模式 定义 当一个对象内在状态改变时允许其改变行为,这个对象看起来像改变了其类。 类型 行为型。 UML类图 角色 环境(Context)角色:环境角色含有状态角色的对象,并且可以处理一些请求,这些请求最终产生的响应会与状态相关。
