设计一个简单的课程管理系统（CourseManager）。主要功能包括： 课程信息的录入。主要包括：课程号（no）、课程名（name）、学分（grade）等； 课程信息的查询。根据课程号、课程名和学分等查询课程的信息。注意：查询结果可能不唯一。 课程信息的修改。根据课程号查询到指定课程的信息，再用新的内容替换。 课程信息的删除。根据课程号删除指定课程的信息。 设计时，采用层次化设计法，将类分为界面层（ui）、功能层（business）和持久层（persistence）3层，放在不同子包中。整个系统的代码放在exe4_2包中。(Design a simple course management system (CourseManager). Key features include: Entry course information. Including: course number (no), course name (name), credits (grade) and the like Queries course information. Information based curriculum, course name and credit and other inquiries courses. Note: query results may not be unique. Modify course information. Inquiry based curriculum to the specified courses, and then replaced with new content. Remove course information. Remove a specified course of information based curriculum. Design, the use of hierarchical design method, the class is divided into the interface layer (ui), the functional layer (business) and persistence (persistence) 3 layers in different sub-packages. The system code in the exe4_2 package.)

建立类的层次结构。 创建如下图所示的类 使用类层次结构中的类 Employee ： 姓名，保险号、 SalariedEmployee 周薪 CommissionEmployee 佣金率、销售总额 HourlyEmployee 每小时的工资和工作小时数 BaseplusEmployee 每周的基本工资数 (Create a class hierarchy. To create a class as shown Use classes in the class hierarchy Employee: name, insurance number, SalariedEmployee weekly earnings CommissionEmployee commission rates, total sales HourlyEmployee hourly wages and the number of hours worked BaseplusEmployee weekly basic wage)

均值变点是统计学中常用的变点分析方法，其主要思想如下： 假设有一组数据，随着某个指标变化（增大），其值逐渐增加并趋于稳定，如何判断在这个过程中是否出现了突变的情况，异样的情况？ 均值变点分析方法提供了一种思路，大概如下： 1 计算总的均值和方差； 2 循环将这组有序数据分成两组，X1，X2 计算各组的均值和方差， 计算总方差与分组方差之和的差； 3 得到变点(The change point of mean is a commonly used change point analysis method in statistics. Its main ideas are as follows: If there is a set of data, as a certain index changes (enlargement), its value increases gradually and tends to be stable. How to judge whether there is a sudden change in the process and the unusual situation? The mean change point analysis method provides a way of thinking, which is as follows: 1 the total mean and variance are calculated. The 2 cycle divides the ordered data into two groups, X1, X2. Calculate the mean and variance of each group. The difference between the sum of the total variance and the group variance is calculated. 3 get a change point)
