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.　　入伍后，秦观变身魔鬼教官，要求严苛，新兵训练结束，三位同学一起被分到新组建的特勤第八组，队长正是秦观。经过几经的坎坷，刘小念终于下定决心要去南方闯荡了。他满怀深情的与黄家告别，可刚出门就被守在门口的警察逮个正着。原来上市公司是个骗局，他去南方发展的计划也泡了汤。
