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.

自从Adobe公司1993年第一次发布公共PDF参考以来，支持各种语言和平台的PDF工具和类库就如雨后春笋般涌现。然而，Java应用开发中Adobe技术的支持相对滞后了。 　　自从Adobe公司1993年第一次发布公共PDF参考以来，支持各种语言和平台的PDF工具和类库就如雨后春笋般涌现。然而，Java应用开发中Adobe技术的支持相对滞后了。这是个奇怪的现象，因为PDF文档是企业信息系统存储和交换信息的大势所趋，而Java技术特别适合这种应用。然而，Java开发人员似乎直到最近才获得成熟可用的PDF支持。 　　PDFBox（一个BSD许可下的源码开放项目）是一个为开发人员读取和创建PDF文档而准备的纯Java类库。它提供如下特性： 提取文本，包括Unicode字符。 和Jakarta Lucene等文本搜索引擎的整合过程十分简单。 加密/解密PDF文档。 从PDF和XFDF格式中导入或导出表单数据。 向已有PDF文档中追加内容。 将一个PDF文档切分为多个文档。 覆盖PDF文档。(The Apache PDFBox library is an open source Java tool for working with PDF documents. This project allows creation of new PDF documents, manipulation of existing documents and the ability to extract content from documents. Apache PDFBox also includes several command-line utilities.
