SSH实现的商城项目,就是基本的商城项目，内含数据库(Shopping Mall Project Implemented by SSH)

说明：  天天酷跑代码 包含源代码 图片资源 代码内有注释(Everyday cool run code)

java做的计算器，JFrame，自己做的作业，有需要的下载(java calculator to do, JFrame, do their own work, there is a need to download)

说明：  Mybaties 的基础入门2，这个是第二部分内容 开发工具 IDEA， TomCat，SQL(Introduction to Mybaties 1, Development tools IDEA, TomCat, SQL)

Xlet will be visible on-screen, so we extend org.havi.ui.HComponent(NOT java.awt.Component). it also implements java.awt.KeyListener to receive keypresses an RCU

银行ATM机的设计及实现.包括UML建模和JAVA实现的源代码呀.极品中的极品.(bank ATM machine design and implementation. Including the UML modeling and JAVA source ah. Acura's head.)

说明：  因为某些国家的进口管制限制，Java发布的运行环境包中的加解密有一定的限制。比如默认不允许256位密钥的AES加解密，解决方法就是修改策略文件。(Because of the restrictions of import control in some countries, there are some restrictions on the encryption and decryption in the operating environment package released by Java. For example, AES encryption and decryption of 256 bit key is not allowed by default. The solution is to modify the policy file.)

2.设计一个简单的课程管理系统（CourseManager）。主要功能包括： (1)课程信息的录入。主要包括：课程号（no）、课程名（name）、学分（grade）等； (2)课程信息的查询。根据课程号、课程名和学分等查询课程的信息。注意：查询结果可能不唯一。 (3)课程信息的修改。根据课程号查询到指定课程的信息，再用新的内容替换。 (4)课程信息的删除。根据课程号删除指定课程的信息。 设计时，采用层次化设计法，将类分为界面层（ui）、功能层（business）和持久层（persistence）3层，放在不同子包中。整个系统的代码放在exe4_2包中。(2. Design a simple course management system (CourseManager). Key features include: (1) entry program information. Including: course number (no), course name (name), credits (grade) and the like (2) information about courses. Information based curriculum, course name and credit and other inquiries courses. Note: query results may not be unique. (3) Course modify information. Inquiry based curriculum to the specified courses, and then replaced with new content. (4) Delete course information. Remove a specified course of information based curriculum. Design, the use of hierarchical design method, the class is divided into the interface layer (ui), the functional layer (business) and persistence (persistence) 3 layers in different sub-packages. The system code in the exe4_2 package.)
