B) Design principles. Many people have listed seven principles, such as single duty principle, opening and closing principle, Richter substitution principle, dependence inversion principle, interface isolation principle, composite reuse principle and Dimit principle. LSP, I elevated it to one of the three cornerstones of the object-oriented paradigm; Single responsibility and interface isolation are mainly used as the principle of responsibility division in object-oriented analysis/OOA, which you can not pay much attention to at this time. Relying on the inversion principle, I throw it away as garbage, because the opening and closing principle or directly "relying on abstract type principle" already contains the essence of relying on the inversion principle, while the dross of relying on the inversion principle is inherited by IoC. Of course, the pullback, I emphasize very much. Therefore, you need to master the abstract dependency principle (OCP), one-way dependency principle (including the learning of callbacks) and the minimum dependency principle (composite reuse principle, Dimit rule).In short, the proxy mode provides an interface consistent with the real class, which is intended to be used to proxy the class to access the real class, the skin mode is intended to simplify the interface, and the adapter mode is intended to transform the interface.With the evolution of human beings, the methods we try to destroy each other are also evolving. The emergence of the Internet gave birth to a new war, a quieter war. One mode of warfare is real-time long-range scattered attacks and anonymous warfare. A kind of war with robots and unmanned aerial vehicles as the main force, attacking according to our requirements, or artificial intelligence as the strategist.怎么都跟约好似的，都奔福缘茶楼来了？不等回答，又咦了一声，问道：小弟听说，你们两家都要回乡去，都告了假了。被唤作青蒜的孩子约莫**岁，细瘦的身材，黄黄的小脸，抬头怯怯地问红椒道：二姐姐，你不进来么？听声音，是个女娃子。即便是韩信第六四六章越王行踪原谅他，他自己都很难过自己这一关。天下三分，烽火四起，在这个英雄辈出的时代，战争不仅有刀光剑影，亦不只是血肉搏杀。秘密情报线上的生死角逐，正涌动于滚滚洪流的阴影当中。
