One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code. Because the abstract factory is not very easy to understand, let's look at the diagram first, and then it is easier to understand with the code.探长吕良伟送临盆在即的妻子刘瑞琪往医院，突然收到警署急召他往制止一宗持枪抢劫案，伟到现场，追捕中伟击毙洪涛、洪乔，贼兄洪浪目睹弟妹惨死，虽被警察制服，仍叫骂誓向伟报仇。伟急忙前往医院，妻已诞下一对双胞胎，伟赫然发现两个婴儿额头上都有一颗红胎痣，与涛及乔身亡的枪伤一模一样，伟有不祥的感觉。幸而时间冲淡心中的阴影，伟十分痛爱一双儿女。转眼间，儿女已有一岁了，怪事开始接连发生在伟的身上，令伟心中的阴影再次浮现，究竟这双爱儿是否涛及乔的鬼魂转世？伟不愿去相信，但事情一再发生，每次都危及他的生命，伟极感困扰，更接获洪浪逃狱的消息，知道这个狂人会来找他报仇。内忧外患，令伟陷于崩溃边缘，导致工作上出错，Love you don't know how to live or die love you smelly shamelessLiskov Substitution Principle, LSP (Richter Substitution Principle) means that subclasses must replace their parent types. In other words, in the process of software development, after the subclass replaces the parent class, the behavior of the program is the same. Only when the subclass replaces the parent class and the function of the software is not affected can the parent class be truly reused, and the subclass can also add new behaviors to the parent class. In order to look at an example of violation of LSP principles, the specific code is as follows:Article 26 of the Law on the Protection of Women's Rights and Interests stipulates that no unit may dismiss female employees or unilaterally terminate labor contracts on the grounds of marriage, pregnancy, maternity leave, lactation, etc.Third: to get timely feedback, you can give advice through experts, who can be around you or a big V in a certain aspect of the network.江湖早已不再平静，偏安一隅的五圣教屡遭加害，破败的枫华谷村庄莫名异动。重出江湖的阿萨辛，新登场的曲云和阿亮……流落清水岛数年的沈剑心突然遇袭，这次他又会面临怎样的危机？
