If I were to implement a pizza ordering system, I would definitely write the code like this, because this kind of code can be written subconsciously without consuming our brains. However, take a closer look at this code: the purpose of this method is to order pizza. However, the code for ordering pizza also needs knowledge about the production of pizza. This method must know all pizza. Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza.
电影《小小家长》是一部由北京华影卫士影视艺术交流中心联合河南相见未晚文化文化传播有限公司出品，是田刚磊编剧导演“小小”系列三部曲的第二部作品，该系列电影分别是《小小校长》、《小小家长》、《小小团长》。影片中9位小主角均选自漯河市和临颍县，并且孩子们都是第一次出演电影。影片主要讲述实验小学郭校长看到现在家庭大多都是独生子女，非常娇生惯养，就在学校进行一次“小小家长”的活动。众多学生开始当家作主管理家务，才知道父母亲辛苦工作挣钱养育自己是多么的艰辛，小脾气有了很大的转变，此举也受到社会和家长们的欢迎。该影片2018年暑假在河南漯河拍摄，计划于2019年7月在全国电影院线上映。
电影剧本会由侯孝贤和朱天文以及阿城帮忙打造，目前定下的演员只有舒淇和张震，金城武、浅野忠信等人也在接洽中。《聂隐娘》对侯孝贤的最大挑战是商业诉求，他的作品除了出道时候的喜剧片和少数几个片子，其他无一例外丧失了本岛市场，只能走上无奈的国际影展路线。侯孝贤如何在商业导向的压力下保持个人风格以及创作自由，他能作出何等改变将是一大看点。此外由于杨德昌没能完成北宋的追风少年（资金缺口太大），侯孝贤梦回唐朝的侠女传奇更是多出一番意义。

We understand through the monomer pattern that the monomer pattern is created in the form of literal quantity of objects. For example, the following object literal quantity method code is as follows:
The combination mode is also called part-to-whole mode. The combination mode combines objects into a tree structure, which is used to represent the relationship between the whole and the part. The combination mode enables clients to treat individual objects and combined objects equally. For example, in. NET, simple controls such as WinForm controls, TextBox and Label inherit from the Control class, while composite controls such as GroupBox also inherit from the Control class. The specific structure diagram of the combination mode is shown below.
