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.云青山坐在麻城上看到眼前的景象之后心中感慨，越国山阴如此之繁华，江东之地也很是安定，百姓可谓是安居乐业，当真是好。NHK第49部大河剧。以三菱財閥創業者岩崎弥太郎的視点出发,描述坂本龙马33年的生涯。本剧为原创剧本，将以幕末时首屈一指的企业家岩崎弥太郎的观点出发，岩崎弥太郎与阪本龙马同样出身土佐藩，两人之间曾有深交，弥太郎并且在龙马的海援队担任过会计职务。明治维新後，弥太郎也开创了三菱财团。 　　本剧为大河剧史上第二度将坂本龙马的一生搬上萤幕，上一回以龙马为主角的大河剧，是1968年的《龙马来了》（改编自司马辽太郎的小说）。本剧的剧本则由《HERO》等著名日剧的编剧福田靖所撰写。魏铜怔了一下，也急忙赶了上去。她点头道：若是别的事，还可恕。《看了又看》好看的原因，在于它表现的是没有虚假矫饰的百分之百的平常生活。在犹如小河淌水般静静流过的100多集故事里，没有大起大落的情节，也没有豪华的场景，说的是几对年轻人在追求理想爱情中的快乐和苦恼，婆媳之间、夫妻之间、妯娌之间相处中的矛盾和无奈，这些平淡朴素的琐事，却让人感到特别真切，就像发生在自己身边的事，处处流露出令人感动的亲情和温馨，其中蕴涵着很多做人的道理。观众从中可以触摸到普通韩国家庭的真实生活状态，看到韩国人传统的家庭观念与新的生活观念的冲撞。爱情，清澈纯净《看了又看》写了三对年轻人的爱情，这些爱情戏并没有用三角恋、婚外情或凶杀案做“浇头”，剧中甚至很少有接吻的镜头，但这些清澈纯净的爱情却显得格外动人。比如，银珠为了让未来婆婆接受自己，一次次上门看望长辈，却每每遭到冷落和羞辱，甚至被拒之门外在大雨中淋得湿透。基丰为了博得金珠妈妈的好感，一改爱睡懒觉的习惯，每天天不亮就陪丈母娘去山上打泉水、锻炼身体……这些几乎不掺杂质的爱情深深打动了观众。《花开时想月》为韩国KBS2于2021年下半年播出的月火连续剧,由《月桂树西装店的绅士们》,《监狱医生》的黄仁赫导演与金珠熙编剧合作打造。此剧讲述朝鲜禁酒令时期,四个越线的年轻人的友情和爱情以及成长故事。
