JAVA开发的聊天通讯系统, 值得学习. java聊天系统_eclipse开发_access数据库(JAVA Developer Chat communication system, it is worth learning java chat system _eclipse developed _access database)

家政服务小程序。适合预约上门家政服务项目店铺使用(Housekeeping Service Procedure)

fragment 应用示例，以微信界面为例

说明：  多媒体mp3播放器，java代码，可能有不足之处。。。。(Multimedia mp3 player)

Java提供的API类BigDecimal，用来对超过16位有效位的数进行精确的运算。双精度浮点型变量double可以处理16位有效数。在实际应用中，需要对更大或者更小的数进行运算和处理。(BigDecimal Java API classes provided for more than 16 significant bits of the number of precise calculations. Double-precision floating-point variables can handle double the number of 16-bit effective. In practice, the need for a larger or smaller number of computing and processing.)

源码和依赖的jar包都在压缩文件里 test目录下有行情的demo，交易部分的API还没完全做好，可以连上前置和登录 这个java接口算是预览版吧(Source code and dependent jar packages are all demo in the test directory of the compressed file. The API of the transaction part is not yet complete. You can connect the pre-and login java interface as a preview version.)

说明：  针对复杂的传统Java智能卡指令解析问题,结合Applet的部署特点,提出了指令预解析的概念 给出了转换后的Applet文件(CAP,Converted Applet file)中导入组件、常数池和导出组件的预解析优化存储结构及包注册表结构,使用定长存储结构替代原有的变长存储结构以加快查找过程,引入了导出组件辅助索引表以加快外包类的解析过程 设计了基于优化后组件的静态域、静态方法和类访问字节码指令的快速解析流程,将解析算法的时间复杂度降为常数阶 在Applet下载过程中通过预解析来生成优化后的组件存储结构,在执行过程中依据快速解析流程来完成静态域、静态方法和类对象的快速访问,从而缩短了Applet运行时的解析时间.测试结果表明,在不改变标准Applet下载、运行流程的情况下,该方法有效地减少了卡内存储器的访问次数,缩短了解析算法的执行时间,提高了Applet执行的整体性能. (For a complex of traditional Java smart card command parsing problems with the Applet deployment characteristics of proposed pre-analytic concept of instruction gives converted Applet file (CAP, Converted Applet file) to import components and export components of constant pool pre-analytical optimization of storage structure and package the registry structure, and the use of fixed-length storage structure replaced the original variable-length storage structure to speed up the search process, the introduction of secondary index table to export components to speed up the resolution process outsourcing category designed based on optimization After the components of the static fields, static methods and class byte code instructions to access the rapid resolution processes, analytical methods will be reduced to constant time complexity order in Applet download process through pre-parsing to generate the optimized storage structure components , in the implementation process based on rapid)

Java的学习笔记，对于初学者来说这是个重点，上手会比较容易(Java learning classical notes)

通过写好的最小DFA实现源码的分词功能。 内容：GetToken.java（源码）SourceCode.txt（要分词的源码） Tokens.txt（Token序列）(Achieve source word feature written by minimal DFA. Content: GetToken.java (source) SourceCode.txt (word to the source) Tokens.txt (Token sequence))

管理cert的工具使用java.一定要下哦(mange cert took in java)
