In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.刘邦不由的心头一紧，这样的情况相爱确实对汉军有些不利。莱斯利希望能在国家公园管理局的一块土地上中标，但面临着包括她的新死敌罗恩·斯旺森在内的一个团体的竞争。同时安迪和阿普里尔是m。yakubd.cc担心他们现在又老又无聊。梅老师儿子韩思慕过生日，性格火爆的二姐韩思林看不惯弟弟毕业七年，一心想当作家且一事无成“傍老”行为，不顾大姐韩思杨和丈夫程实的劝告，二人发生争执把生日过得不欢而散……梅老师第二天突然昏倒在课堂。作CT检查，他的学生医生王大力发现她得了脑癌，且无法手术，生命长则一年，短则三五个月……悲痛欲绝的梅老师让王大力替她保密，决定自己承载一切苦难，要在有限的时间内把子女的事安排好。二女儿思杨因嫌丈夫程实不按照她给设定的生活轨迹去做，使二人在生活、事业、理念上出现分歧，情感产生裂痕，反埋怨程实不思进取，欲离婚遭到母亲反对，决定自己考博改变家中的生活状态。生活受到极度压抑的程实，在网上以长发飘飘的网名来寻找自己初恋时妻子可爱的影子，让思林发现后反加深了对他的误解，但是没想到才华横溢的程实被自己的研究生于菲菲看中，爱上了他。儿子思慕无工作，无对象，又无成果，成了梅家老大难。梅老师担心自己走后儿子不能独立生存，急于让大女儿思杨帮找工作，求李老师给介绍对象，而一心要当作家的思慕不领情，一一回拒。对门规划处长聂mai为了生计假扮人妖，成为了炙手可热的新星，并认识了ter这个导演，成功地让ter为自己动了心动了情，于是一场爱与性别的博弈在男主的心里开启……Ariyun
