java学习书籍，java设计模式，适用于初学者，，内容详细丰富(java learning books)

说明：  设计模式一（单子、工厂、策略模式）练习 1． 假设现在要设计一个贩卖各类书籍的电子商务网站的购物车系统。对所有的教材类图书 实行每本一元的折扣；对连环画类图书提供每本7%的促销折扣；而对非教材类的计算机图书有3%的折扣；对其余书没有折扣。使用策略模式、工厂模式、单子模式进行设计(Design Mode 1 (List, Factory, Strategy Mode) Exercise 1. Suppose we are going to design a shopping cart system for e-commerce websites that sell all kinds of books. All textbook books are discounted at one yuan per book; comic books are discounted at 7% per book; computer books are discounted at 3% for non-textbook books; and other books are discounted at no rate. Design using strategy mode, factory mode and single mode)

创建四个类，分别为Employee类、SalariedEmplyee类、HourlyEmployee类和CommissionEmployee类。其中Employee类是其他三个类的父类。Employee类包含姓名和身份证号。除此之外，SalariedEmployee类还应包含每月工资；HourlyEmployee类还应包含每小时工资数和工作时间数；CommissionEmployee还应包含提成比例和销售总额。每个类都应有合适的构造方法、数据成员的设置和读取方法。编写一个应用程序，创建这些类的对象，并输出与对象相关的信息。注意子类有时需调用父类的构造方法和被覆盖的方法，成员变量定义为private,对有些方法实现重载。 (Create four categories, namely the Employee class, SalariedEmplyee class, HourlyEmployee classes and CommissionEmployee classes. Employee class is the parent class where the other three classes. Employee class contains the name and ID number. In addition, SalariedEmployee class also includes a monthly salary HourlyEmployee class should also include the number of hourly wages and the number of working hours CommissionEmployee should also include the proportion and total sales commission. Each class should have the right to set and read the constructor method, data members. Write an application to create objects of these classes, and output information associated with the object. Sometimes need to call attention to a subclass of the parent class constructor and methods are covered, member variables defined as private, to achieve overloading of some methods.)

基本算法： 采用博弈比较常用的策略。 计算机下子前，分别对玩家和电脑棋型进行评估，然后根据棋型对每一位置打分（玩家和电脑在同一点的分数不同），比如活三100分，冲四1000分等，然后根据每个落子点分数进行选择。采用极大极小值策略，进行多步计算。(Basic algorithm: The game strategy is commonly used. Before computer playing, players and computer chess models are evaluated separately, and then each position is scored according to the chess pattern (players and computers have different scores at the same point), such as live three hundred points, go four thousand points, and then choose according to the score of each falling point. Multi-step calculation is carried out by using the minimax strategy.)

分布式温控系统基本要求 1. 中央空调是冷暖两用，但一次只能使用一种温控装置。当设置为供暖时，供暖温度控制在25°C～30°C之间，当设置为制冷时，制冷温度控制在18°C～25°C之间。 2. 中央空调具备开关按钮，只可人工开启和关闭，中央空调开启后处于待机状态。当关闭后，不响应来自房间的任何温控请求。当有来自从控机的温控要求时，中央空调开始工作。当所有房间都没有温控要求时，中央空调的状态回到待机状态。 3. 房间内有独立的从控空调机，但没有冷暖控制设备。从控机具有一个传感器，实时监测房间的温度，并与从控机的目标设置温度进行对比，决定是否需要制冷或制热，并向中央空调机发出请求。如果从控机发出的请求和中央空调设置的冷暖控制状态发生矛盾时，以中央空调机的状态优先，即中央空调机不予响应。 4. 从控机只能人工方式开闭，并通过控制面板设置目标温度，目标温度有上下限制。所有房间的初始目标温度由中央空调机设置，每个房间的空调机开启时要读取中央空调机预置的房间温度。温度升降范围应该在目标温度的上下1 °C。房间不考虑大小和管道的分布及大小问题，在达到目标温度后，房间的温度每分钟上下变化0.1°C。 (Basic requirements of a distributed temperature control system 1. Central air conditioning is the well-being of dual-use, but can only use a thermostat device. When set to heating, the heating temperature at 25 ° C ~ 30 ° C, and when set to cooling, the cooling temperature at 18 ° C ~ 25 ° C between. 2. Central air conditioning with switch buttons can only be manually opened and closed, central air-conditioning turned on in standby mode. When closed, do not respond to a request from the room of any thermostat. When the machine from temperature control from the control requirements, central air-conditioning work. When all rooms are no thermostat demand, central air condition back to standby. 3. Room independent from the control air conditioning, but no climate-control equipment. From the control machine with a sensor, real-time monitoring the temperature of the room, and with the goal set from the control unit compares the temperature to determine the need for cooling or he)
