说明：  用java实现获取系统的mac地址，课堂上的资料进行复习。(get system mac address)

比较方便的地图制作小工具，我们做java游戏时经常用到(Convenient to map production of small tools, we make java games frequently used)

sendtcp java 发送tcp包的程序,基于winpcap,jpcap(sendtcp java Send tcp packet procedures, based on winpcap, jpcap)

说明：  完全仿照慕课网开发，前端的课程选择，课程分类等等，后台的课程管理，讲师的管理 ，对网站流量的统计，等等十分精美，基本不需要二次开发就可以满足视频学习类网站的需求(It is completely imitated by Mutu Net development, front-end course selection, course classification, etc., back-end course management, lecturer management, statistics on website traffic, etc. It is very beautiful, and basically can meet the video learning website without secondary development. Demand)

Struts力图从整体上减轻构造企业级Web应用的负担，并提供国际化和数据库连接池支持。Struts体系可以看成两个相对独立的部分：第一个部分是Struts API，用于编写支持Struts的应用组件；第二部分是Struts的JSP标记库，由html、bean、logic和template四个标记组成(Struts structure seeks to reduce the overall burden of enterprise-class Web applications and provides internationalization and database connection pooling support. Struts system can be seen as two relatively independent parts: The first part is the Struts API, used for the preparation of the application components to support Struts second part of Struts' s JSP tag library, from html, bean, logic, and template of four markers composition)

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.)

说明：  基于spring-ehcache的项目缓存案例。(Project caching case based on spring-ehcache)

说明：  一款一个益智类的手机游戏源码,可自己进行编译生成相应的安装文件(A puzzle class of mobile game source code, can be compiled to generate the corresponding installation files.)
