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.UK: 908,000十余俘虏满脸颓丧与惊恐，相比于此前俘虏过的卡内利亚斯，他们显然更加不相信眼前发生的事情。《鉴爱男女》是由芳草地影视出品，腾讯视频独家播出的轻喜微网剧。故事主要围绕着三位性格迥异的合租密友的日常生活与各自的情感关系而展开，外表可爱、内心狂野、缺爱不可独活的戏精傻白甜小爱（吴静怡饰），年纪不小、心思不少、看似聪明却总被骗的大龄御姐梦露（许婉饰），了解男人更了解女人、自称“鉴渣利器”的毒舌丑萌男闺蜜萌萌（刘闯饰），她们拥有着共同的标签——单身汪！穿插她们在脱单故事中的各类型男友既使得本剧呈现了欢乐轻松的喜剧风格，也生动描绘了全面而又实用的“鉴渣百科全书”。我来找少爷，有两桩事要说。
