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.东北老汉赵本山因为女儿闹离婚痛失爱孙，只得假扮保姆混入女婿家，不料却引来亲家爷郭达和邻居老头的爱慕和追求，这个荒唐的局面让人忍俊不禁，而赵本山的老太太装扮更让人捧腹，当他忸怩作态时连剧组人员也认他不出。The eldest son of the Lins
