面对大皇子派来的说客，他咳嗽一声道：我们家呢，大部分事都是本官做主。板栗和魏铁都笑了起来。On the morning of May 15, 2013, Aunt Liu was busy in the kitchen early. This morning, her son and daughter-in-law had an appointment to go home for breakfast. After waiting for a long time and seeing no one, Aunt Liu called the couple. As a result, both phones were turned off. Aunt Liu waited until more than ten o'clock. When the food was cold, she did not say anything about her son and daughter-in-law. Aunt Liu was a little panicked and hurried to her son's house. She pushed her son's door and found that the door was left unlocked. When she approached the door, she found no one in the living room. "What's the matter with you? Your cell phone is turned off!" Aunt Liu shouted loudly, but no one answered. She could only continue to walk to the bedroom. "What did I say you were doing?" Aunt Liu knocked on the bedroom door and asked, but no one answered. She pushed open the bedroom door and saw that the bed was clean and the couple was not at home.

For example, the buttons on the page and so on, For example, how to operate the specified buttons, What happens when the button is clicked, We don't know, We don't know what their business is. Of course, what we know will definitely be a click event. We don't know exactly what business to deal with. Here we can use command mode to deal with it: after clicking the button, we must send requests to some objects responsible for specific behaviors, which are the recipients of the requests. However, at present we do not know what the receiver is or what the receiver will do. At this time, we can use command mode to eliminate the code coupling relationship between the sender and the receiver.In the previous example of electric lights, a state mode program was completed. First, the Light class is defined, which is also called Context here. Then in Light's constructor, to create instance objects for each state class, Context will hold references to these state objects in order to delegate the request to the state objects.
