Simple factory, all things have been done in one place. However, the factory method creates a framework for subclasses to decide how to implement it. For example, in the factory method, the OrderPizza method creates a general framework to create pizza. The OrderPizza method relies on the factory method to create specific classes and make actual pizza. It is possible to decide what the actual products manufactured are by inheriting the factory. Simple factories do not have this flexibility.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.忙乱中，史班头把大夫也找来了，是秦枫和云影。52赫兹，代表着一种没有同类能接收的频率，就是“孤单的人，我爱你”。孤单，正是所有爱情故事的开始……在拥挤的都市中，围绕着各种孤单的人群，没有勇气尝试爱情滋味的年轻男女、为经济压力所苦的爱情长跑恋人、受世俗羁绊的中年单身人士、相爱却不被认同的同性情侣…《52赫兹我爱你》描写在全世界都为爱情庆祝的这一天，终于轮到渴望爱情的他/她们担当主角，谱写出浪漫甜蜜的恋曲。
