GPS定位，在android4.4下编译通过，可供参考学习(GPS positioning, android4.4 compiler, available for reference study)

说明：  本系统采用struts+spring+hibernate架构，重在讲述三者结合在一起的应用开发，所有源程序都有详细的注释，供入门者学生参考，未经作者允许不得用于商业用途，只能用于教学或个人学习。 程序只是整个系统中的一个模块，用于和各位程序爱好者交流之用。 使用方法： (1)在oracle数据库中运行数据库脚本文件cnc.sql. (2)用eclipse(或其它开发工具)直接导入工程. (3)将spring配置文件applicationContext.xml中数据库连接地址改为您自已的地址。 (4)部署到tomcat服务器中即可运行(jdk1.5以上). 用户名和密码均为：admin(The system uses struts+ Spring+ Hibernate framework, focusing on the three combined application development, all have detailed source notes, for beginners to students without author permit shall not be used for commercial purposes, can only be used in teaching or individual learning. Procedures for the entire system is only one of the modules, and all procedures for lovers to exchange purposes. Usage: (1) in the oracle database to run the database script file cnc.sql. (2) to use eclipse (or other development tools) directly into the project. (3) spring configuration file applicationContext.xml in the database connection address changed your own address. (4) deployed to the tomcat server to run (jdk1.5 and above). A user name and password are: admin)

this is answer for ssd7 exercise 4

说明：  java界面设计，适合初学者！欢迎下载，大家交流学习。(java interface design, suitable for beginners! Welcome to download, the exchange of learning.)

说明：  拍卖算法，可以用来学习分布式拍卖算法，了解原理，希望对大家有帮助(this is the distributed auction algorithm developed by Java, hope help anyone who need it!)

说明：  建立快速索引，FastIndex为抽象类，AscFastIndex和DescFastIndex分别为两个实现(Quick Indexing. FastIndex is an abstract class and AscFastIndex and DescFastIndex are two implementations respectively.)

liferay portlet 实例，可以直接部署(liferay portlet instance, can be directly deployed)

说明：  一个应用线程实现指针运动的指针时钟程序。程序应用绘制函数时钟面板，根据线程休眠时间间隔，每隔1000ms进行一次重绘。程序通过获取系统时间函数并加以计算个指针位置，再利用绘制函数将其绘制在面板上，通过设置指针长度及颜色，实现时针、分针、秒针的区分。次外，通过获取窗体大小，设置圆面圆心坐标及半径，可依据窗口大小动态划分圆面大小，并动态绘制刻度点位置。(A pointer clock program that uses threads to implement pointer movement. The program draws the function clock panel and redraws it every 1000ms according to the interval of thread dormancy. The program obtains the system time function and calculates the position of a pointer, then draws it on the panel by drawing function. By setting the length and color of the pointer, it achieves the distinction of clockwise, minute and secondhand. Secondly, by acquiring the size of the form and setting the coordinates and radius of the circle center, the circle size can be dynamically divided according to the size of the window, and the location of the scale points can be dynamically plotted.)

实现简单的学生成绩管理、包括成绩录入、排名、导出不合格成绩等(Realize simple student achievement management, including record entry, ranking, export of unqualified grades, etc.)

说明：  采用Spring、SpringMVC、Mybatis、Shiro，前端采用adminLTE、vue.js、bootstrap-table、tree-grid、layer(Spring, Spring MVC, Mybatis, Shiro, adminLTE, vue. js, bootstrap-table, tree-grid, layer are used in the front end.)
