上世纪三十年代，伪满洲国，四位曾在苏联接受特训的共产党特工组成任务小队，回国执行代号为“乌特拉”的秘密行动。由于叛徒的出卖，他们从跳伞降落的第一刻起，就已置身于敌人布下的罗网之中。同志能否脱身，任务能否完成，雪一直下，立于“悬崖之上”的行动小组面临严峻考验。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.大家收拾细软想要逃走，可是，西北、西面、西南、东南、东北，除了东面的大海，靖国竟是被团团围住了，就算逃也没处逃去，百姓们恐惧加绝望，真如待宰羔羊一般。板栗嗯了一声，道：二叔没说错啊。九岁的安娜和家人居住在柏林，1933年到来，一切都开始发生了变化，在她四周，一个陌生人的画像开始挂满在大街小巷，懵懂的安娜不知道发生了什么。不久之后，她和她的家人踏上了一场逃亡之路，安娜在旅途中充满了好奇和困惑，而她也无法忘记陪伴自己童年的那只粉色玩具兔，可惜兔子早已被落在了柏林的家中，逐渐被黑暗所包围。MyHandler h2 = new MyHandler ("h2");
