Re-understanding OO: Object-oriented programming is an idea to think about software design structure with object-oriented thinking, thus strengthening the object-oriented programming paradigm. Object-oriented features are encapsulation, inheritance and polymorphism. "Do these count?" . So from that beginning, when I design a class, I keep reminding myself of the following three points:上世纪90年代，热血不羁的“钢厂大院才子”胡广来，跟刚调来的社区民警老公安全党愿，惺惺相惜情同弟兄。因姐姐胡芳被流氓强暴，胡广来激愤下失手杀死对方被判死缓，彻底绝望。全党愿毅然担负起了胡广来与这个世界的纽带，在他不断地坚持和感化下，胡广来认真改造减刑，重拾了生活的尊严和希望。就在刑期将满前，胡广来惊闻全党愿被一个叫“史瑞克”的人打死的噩耗……去世前，癌症晚期的全党愿，把胡广来托付给了干女儿梅湘。在梅湘帮助下胡广来学会了自食其力。同时胡广来也开始和梅湘一起秉承全党愿的遗志，帮助那些刑满回乡人员，重新开始生活。The Last Watch Before Work: "Parent-Child Kingdom Dissecting Pregnant Women's Belly Incident"故事从灾难发生后一个月左右开始。不同于国外求生的方式，国内封闭式公寓、生活小区的脱险成了主人公吉伦、迦诺、马克共同的难题。食物与饮水的消耗的导致了三人必须尽快冲出丧尸的围困。艰难的逃生使得迦诺难以持续，而对面楼宇独自逃生的马克离双方唯一求生的汽车近在咫尺。主人公吉伦必须 保证已经深陷危险的同伴们至少有一个团结的方式，可信任的建立在这样的世界中是否可以如同往日?整个世界的灾难变化，人类避难所如何建立，可能面对庞大数量的丧尸群，求生与生存的关系，变得更加模糊不清。For example, the above is only a simple literal quantity structure. All member variables above are accessed through Singleton, but it is not a single mode. Because the monomer pattern has a more important feature, that is, it can be instantiated only once. The above is only a class that cannot be instantiated, so it is not a monomer pattern. Object literal quantity is one of the methods used to create a single pattern;所以，你们在外边，不要随意做烂好人。
