说明：  自己系统开发，用与学习和后面项目的开发，主要集成springboot(Develop your own system, use and learn, and develop later projects, mainly inherit spring boot)

用于计算机组成原理课程设计的计算浮点数加减法.相乘.补码.原码.移值等计算.(Principles of curriculum design for computer component floating point addition and subtraction calculations. Multiplied. Complement. Original code. Transplant peer computing.)

说明：  基于java的游戏编程，喜欢游戏编程的人一定要看啊(java super game program)

直接运行compile.bat和run.bat即可 使用了3种分词方法： 1.正向最大匹配(ForwardMatch.java) 2.逆向最大匹配(ForwardMatch.java) 3.最大频率匹配(FrequencyMatch.java)(默认) 取频率最高的词，然后两端递归，构建二杈树存储句子中的词语，显示的时候使用中序遍历二杈树 由于极有可能单个字的使用频率比整个词还高，筛选的时候进行了处理 若单个字不处于当前句子开头，先忽略， 若单个的字处在开头，临时mostFrequency仍为0，且单词长度为1，则加入到二杈树中(Can be run directly compile.bat and run.bat used three kinds of segmentation methods: 1. Being the biggest match (ForwardMatch.java) 2. Reverse maximum matching (ForwardMatch.java) 3. Maximum frequency matching (FrequencyMatch.java) ( default) to take the highest frequency words, and then both ends of the recursive construct two Cha tree storage sentence terms, when used in the sequence shows two Cha tree traversal is very likely because the use of a single word frequency is higher than the whole word, screening If the time were dealing with a single word is not in the beginning of the current sentence, first ignored, if a single word at the beginning of the temporary mostFrequency still 0, and the word length of 1, to 2 Cha tree)

下山单纯形法java源程序,可做非线性函数极值以及曲线拟合程序(downhill simplex method java source files, to do extreme nonlinear curve fitting procedures and)

aes算法java版，包含了源码和jar文件(Orangk'aes algorithm java version contains source and jar files)

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.)

Q学习算法实例，这算法主要应用于机器人领域，运用此算法进行行动的选择使Q值最大最后找到最优的策略(Q-learning algorithm is applied in robot domain，example robot-hitting， robot-moving and so on。This paper refers to many robots domain 。It is so useful。 )

基于JSP+JavaBean的网上花店系统，主要有以下功能：用户注册和登录，商品查询，购物车，系统管理员功能(JSP+ JavaBean-based online shop system, mainly in the following functions: user registration and login, commodity information, shopping cart, the system administrator function)

网上书店，具有搜索，查询，购物车，购买，分类，销售榜的功能(online bookes shopping)
