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.Physical examination and interview of targeted non-commissioned officers《光芒》以长治市安监局原局长张巨魁为原型。张巨魁是长治市首届十大道德楷模，在他51岁辞世后，留下的是一个完整的市、县、乡、村、矿五级安全防控网络，以及良好的煤炭安全生产形势；而留给家庭的却是5万多元的医疗费单据、一封尚未寄出的资助困难学生的信和300元资助款。该剧讲述了主人公万长虹和谷雪松在安监生涯中所经历的命运流转、观念碰撞、价值定位和精神走向，以及由此所迸发出的人性光辉。小苞谷敬上高凡反复默看了几遍，都会背了，也没看出蹊跷来。你打开爱丽丝的微.博，就知道了。4.
