Let's first list a column in life to illustrate the following command mode: For example, we often buy things on Tmall. Then place an order, I want to receive the goods after placing the order, and hope that the goods are true. For users, it is not concerned about how the seller delivers the goods after placing the order. Of course, the seller also has time to deliver the goods, such as delivering the goods within 24 hours. Users do not care about who the express delivery is to, and of course some people will care about what the express delivery is. For users, it is only necessary to deliver the goods within the specified time and generally receive the goods within a considerable time. Of course, the command mode also includes cancellation orders and redo orders. For example, after we place an order, I suddenly don't want to buy it. I can cancel the order or place the order again (i.e. Redo the order) before delivery. For example, I took the wrong size of my clothes. I cancelled the order and took a larger size again.谢谢了。拿下彭城谈何容易啊？汉王虽然现在手中大军众多，可是彭城城池高大，还有彭越率领的不少兵力镇守，想要在短时间内拿下来怕是有些困难。However, writing code in this way has the following disadvantages:Test Scenario 1: Repeat to Jump Yourself (Set SingleInstance Yourself)Source: Brother Guo
