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.Fu Confucian Temple is located in Pan Palace, Zhongshan Road, Licheng District. Founded in the early years of Taiping and Xingguo in the Northern Song Dynasty (976 A.D.), it moved back to other places. Daguan moved back to its original place for reconstruction in the third year (1109 A.D.). The existing building still remains the original appearance of the early Qing Dynasty.
