If you are smart enough, you will certainly think of this. To snatch the competitors' customers not only develops the customers of their own products, but also hits the sales of competitors. Such sales are perfect. Competitors' customers already have a more familiar understanding of similar products and are relatively easy to market. When robbing customers, we must pay attention to the fact that we should use legal and compliant methods to find customers reasonably.
The entrance is the place where one-day tickets and single subway tickets are put in. When entering the station, the tickets will be put in and passed quickly. The put-in tickets will pop out in front. Remember to take them away. When leaving the station, one-day tickets and subway tickets also need to be put in. The difference is that one-day tickets will still be popped up, while single subway tickets will not.

Explain that in the OrderPizza method, we do a lot of things, including calling the CreatePizza method to generate a desired pizza, and then doing a series of operations on the pizza. The key point is that Pizza is defined as an abstract class, which means that in the OrderPizza method we don't care what type this Pizza is at runtime, in other words, this is decoupling. The coupling between PizzaStore and Pizza is uncoupled.

If we start from the initial registration, less than 2% of the people will actually become pilots. These people are also very good in terms of physical condition, but in the end most of them cannot fulfill their dream of flying, which shows the strict standards. Those who barely passed the preliminary examination with minor defects will almost certainly be eliminated after entering the school. So I once again advise you to give up, although this advice is a bit cruel. According to my personal experience, it is better to give up at the beginning than to be eliminated at the last moment after hard work. It's better to have short sharp pains than long dull pains!

2. The coupling between the publisher and the subscriber is reduced. The publisher only publishes a message, and it does not care how the message is used by the subscriber. At the same time, the subscriber only monitors the event name of the publisher. As long as the event name of the publisher remains unchanged, it does not care how the publisher changes. Similarly, the seller (publisher) only needs to tell the subscriber (buyer) about the arrival of shoes, regardless of whether the buyer buys or not, or whether he buys other sellers. As long as the shoes arrive, the subscriber can be notified.
