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.彭城，楚王宫无所事事的哥哥为了争夺家产而偷偷带走弟弟，弟弟的突然消失让两只忠犬产生了焦虑，在这个关键时刻，忠犬杜克凭借灵活、专业的技能巧妙的躲开坏人的监视并成功找到、解救了自己的小主人。而后，另外一只忠犬雪狼也主动出击，配合伙伴杜克一起智斗利益熏心的不良团伙。我军某军校开学，一批新兵进入军营。这些新兵来到军校这样一个严格、紧张的新环境，一切都很新鲜，也很苦、很累。军营，一个锻炼意志品质、培养独立人格的地方，渐渐让他们明白了生活和生命的意义……不能表白的爱情……作为一名军人，他们的生命属于祖国，他们的青春属于人民，而他们也是有血有肉的普通人，他们也有七情六欲……　　又到1999年除夕，笃志的心脏病在同一时刻再次发作，当他醒来的时候，再次回到1995年，开始了重复的人生。小草走上前帮忙打水，一边敬佩地看着于嬷嬷。说到底封地小，军队小，诸侯国家的实力弱小了，这话语权本来就小，现在连同生存的权利都在被肆意剥夺。
