此刻番邑县衙大门外，一个中年男子见到壮士的离去的身影，目光闪烁带着几分疑惑，作若有所思状。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.四处旅游、活泼开朗的贝琪(朱丽叶特·刘易斯 饰)路过小镇，与吉伯特一见钟情，两人很快沉浸在甜蜜的爱情中。贝琪对生活的热情也让吉伯特渐渐认识到，除了家人，生命中他也该有属于自己的追求。阿尼就要过十八岁生日了，这是母亲最后的心愿，待这一切结束，吉伯特能有一个不一样的天空吧。脸上烦躁消失无踪，恢复了之前的从容洒脱。Then dig Malaysia:
