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.EventArgs e=new EventArgs ();自此，刘黑皮就忙碌不停，一直到张家人进京。　　张应酬繁多, 把丁托付给次明及其妻. 次明夫妇决意帮助缚住张不羁的心, 丁更决定采取逐个击破的策略, 务求要把张的女朋友一一打发.
