FlyWeightFactory is responsible for creating and managing meta-units. When a client requests, the factory needs to check whether there are eligible objects in the current object pool. If so, it returns the existing object. If not, it creates a new object. FlyWeight is a superclass. When it comes to shared pools, It is easy to think of JDBC connection pooling in Java, Considering the characteristics of each connection, It is not difficult for us to sum up: Applies to several objects that are shared, They have some common attributes, Take the database connection pool as an example, url, driverClassName, username, password and dbname, these attributes are the same for each connection, so it is suitable to use the meta-sharing mode to process, build a factory class, take the above similar attributes as internal data and the others as external data, and pass them in as parameters when calling methods, thus saving space and reducing the number of instances.

For interface programming, a lot of changes that may occur in the system in the future can be isolated. Why? If the code is written for an interface, he can implement the interface with any new class through polymorphism. However, when the code uses a large number of specific classes, once new specific classes are added, the code must be changed. Violating the opening and closing principle.

Code as above; You can see, There are obvious shortcomings, For example, when I click on an element, I need to create a div. I click on the second element to create a div again, We frequently click on such and such elements, and they will frequently create div elements. Although we can remove pop-up codes when we click Close, it is not good for us to frequently create and delete them, especially for performance, and frequent operations on DOM will cause redrawing, etc., thus affecting performance. Therefore, this is a very bad habit. We can now use the monomer mode to realize the pop-up effect. We can instantiate it only once. The following code:
The execution results are consistent with the previous code, but the benefits of using the state mode are obvious. It can localize the relationship between each state and its corresponding behaviors, which are scattered and encapsulated in their corresponding state classes, making it easy to read and manage the code. In addition, the switching between states is distributed within the state class, which makes it unnecessary to write too many if, else conditional branch languages to control the switching between states.
