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.销烟让英国有借口侵华，爱国商人孙维州制造了犀利炮弹，想要报国却被议和派阻拦。杨天淳毅然担起重任，集合众多好友，经过千辛万苦，才将炮弹送到前线，不想朝廷竟然下令停战议和，杨天淳众人最后的抉择是什么呢？JD.com Promises猎人的魂不是手里的枪，而是面对猎物时的智慧与勇气，要比狐狸更狡猾，要比恶狼更凶狠。Requirements　　东北某农场内，生活着一群来自四面八方、身份各异的知青。他们将最好的年华献给了这片黑土地，却不知自己的明天将在何方。恢复高考的消息传到这里，让年轻人们的心再次躁动起来。适逢农场负责人老迟（孙海英 饰）正在酝酿修路计划，只要在建设中取得良好表现就有机会受推荐去年大学。知青们为此蠢蠢欲动，而另有打算的老迟却把机会给了成分不好的女孩陈琼（周显欣 饰）。原来陈琼和老迟的爱将潘志友（王学兵 饰）是一对情侣，他打算借此将二人拆散，让潘扎根于此。然而充满着理想的年轻人是会紧紧抓住这个难得的机遇，还是随波逐流接受命运的安排？
