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.)

Java MongoDb的课程设计资源，系统本身不需要事先写好数据库，系统会在运行时自动创建数据库并插入一条数据，但是运行前请保证数据库（MongoDb）处于开启状态！

编写一个复数类，可以进行复数加法和减法运算。编写一个包含main方法的类（应用程序）测试该复数类。要求该复数类至少包含一个无参的构造方法和一个带参的构造方法；数据成员包括复数的实部和虚部，为double类型；包括两个方法，分别实现复数的加法和减法运算。(Write a complex class, which can add and subtract complex numbers. Write a class (application) containing the main method to test the complex class. The complex class is required to include at least one parametric construction method and one parametric construction method; the data members include the real and imaginary parts of the complex, which are of double type; and two methods are included to realize the addition and subtraction operations of the complex respectively.)
