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.《立春》讲述了蒋雯丽扮演的王彩玲在小县城学校教授音乐，虽然貌不出众，但她却有一副好嗓音，对歌剧尤其着迷。然而，闭塞小县城的普通百姓对歌剧并不感冒，志不得意的王彩玲一心想要调到北京，在那里一展歌喉发挥自己的天才。
