In fact, this is wrong and they do not really master the idea of design pattern. In fact, many times readers use a certain design pattern, but they just don't know what the name of this pattern is. Therefore, when designing programs, we should use appropriate design patterns according to our own understanding.汉朝，淮南王刘安因对上古神话传说感兴趣，被武帝（刘威 饰）使为“离骚赋”，奉旨著书。为收集素材与妻子寻月遍访民间，历经世事，眼见因武帝营宫室、急赋敛、重刑诛而导致盗贼群起、民不聊生，著书锐兴顿减，又因寻月积劳成疾病倒途旅，遂返京上万言谏疏。武帝怒而欲杀之，幸得群臣力保，才于重杖之后 限令三日著成《淮南子》。及至回到家中，方知爱妻已撒手人寰，痛不欲生中挥泪提笔，奋笔二日成书两卷，当写到第五十四篇—后羿嫦娥故事时，因思念亡妻而难以成文，力竭朦寐之中，寻月竟来到眼前，一面替夫磨墨，一面对夫侃侃道出未尽的故事：后羿（李铭顺 饰）如何受天帝之命，斩巨蟒、除八害以救苍生，如何在鸷鸟伤害嫦娥时射鸷鸟以救嫦娥（范文芳 饰）。还说她之所以死后再来相会，只为再次为人再结夫妻缘。说完凌空飞升而去。惊醒的刘安唯见皓月当空，月宫中竟隐现着妻子的身影，于是义思汹涌一夜疾书，青丝尽成白发，终为后人留下后羿射日、嫦娥奔月等旷世神话。The research on classification ability is more in kindergartens and more in primary schools. Research by cognitive psychologists has found that children under 0-1 years old basically have no classification ability, and they mainly rely on individual perception. The classification ability of children aged 1-3 has begun to sprout, but the concept of "category" has not yet formed. The classification of children aged 3-5 is basically still based on external perceptible dimensions such as shape and color. For example, children in small classes in kindergartens are asked to classify red plastic balls, red apples and bananas. They will divide the balls and apples together, either according to the shape (circle) or according to the color (red), but they will not put apple kernel bananas together according to the function (edible). What if you add another celery?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.警官杰克·霍伊特被晋升到了洛杉矶警察局的毒品缉查部，经验丰富的黑人警官阿洛佐·哈里斯负责教杰克一些基本的规条和知识。阿洛佐在那些混乱的街区颇有威望，他仿佛天生具备某种奇特的侦查能力能够迅速找寻到罪案的蛛丝马迹，被同伴们称为“魔幻之眼”。这种神秘的“第六感”使他成为洛城最出色的警官之一。由于人数太多，葡萄牙几百名守军根本不敢踏出城堡一步。
