1.1 作业描述 设计一个生成和显示时间的分布式应用程序，实现以下功能： 1、 一个服务器生成时间，并在多个不同节点的客户端上显示。 2、 客户端有多种时间显示方式，如模拟时钟、数字时钟。 1.2 作业要求 下面是设计时需要满足的四个要求： 1、 打破客户端和服务器开发过程中的紧耦合。 2、 打破客户端和服务器运行时的紧耦合，即不需要固定的机器，不限制客户端的数目等。 3、 允许客户端显示不同的事件。 4、 使用RPC机制或RMI机制。 (1.1 Design a job description to generate and display time distributed applications, the following functions: 1, a time server generates and displays on the client several different nodes. 2, the client has a variety of time display, such as an analog clock, a digital clock. 1.2 Operating Requirements The following is required to meet four design requirements: 1, breaking client and server development process tightly coupled. 2, breaking the tight coupling client and server runtime that does not require a fixed machine, does not limit the number of clients and so on. 3, allows clients to display different events. 4, using the RPC mechanism or RMI mechanism.)

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.)
