Java基本类型，基本类型之间的转化。运算符的使用。(Basic types of Java，Between the basic types of transformation.The use of the operator.)

使用java编写的文件读取显示的软件，代码风格简洁便于读取，使用了java图形进行编写。可以用来功能拓展的二次开发，也可以用来入门学习java的图形化开发。(Prepared using the java file to read the display of the software, the code concise style is easy to read, the use of the java graphics to write. The two development can be used to extend functions, can also be used to the development of graphical java entry learning.)

Text processing often involves matching text against a pattern. Although Java s character and assorted string classes offerlow- levelpattern- matching support, that support commonly leads to complex code. To help you write simplerpattern- matching code, Java provides regular expressions. After introducing you to terminology and thejava.util. regex package, Jeff Friesen explores many regular expression constructs supported by that package s Pattern class. Then he examines Pattern s methods and the additionaljava.util. regex classes. In conclusion, he presents a practical application of regular expressions.(Text processing often involves matching text against a pattern.

使用Java+Ext技术，为小巧的HTMLArea 编辑器加上图片上传功能，因为以前的HTMLArea其它地方都很完美，就是没有图片上传功能，让喜欢她的人望而却步，现在好了，JAVA高手们运用手中的技术，结合目前流行的AJAX框架EXT技术，为她加入了一个插入图片并上传的功能(JAVA gurus use their technology use Java+Ext technology, plus the compact HTMLArea editor image upload feature, because the previous HTMLArea other place is perfect, is that there is no image upload feature, so that people like her flinch now combined with the popular AJAX framework EXT technology, she joined an insert pictures and upload)

实用性代码，可以在手机等移动设备上很好的使用，可操作性强。(Usefulness of the code can be very good for use on mobile phones and other mobile devices operable.)

说明：  专门为kettle这款优秀的ETL工具开发的web端管理工具。 kettle作为非常优秀的开源ETL工具得到了非常广泛的使用，一般的使用的都是使用客户端操作管理，但问题是当投入生产环境使用时，动辄上百或几百个job需要管理，这时在使用客户端管理已经很难完成了。我所知道的解决方案有用命令行的调用的，操作麻烦，总之还是很难用啦，还有就是开发web端管理工具，kettle自带了一个web端管理工具，界面极其简陋不说，还很难用，基本无法投入生产环境使用，其他没留意到还有没有较好对众多job进行管理的工具。(A web-side management tool specially developed for kettle, an excellent ETL tool. Kettle as a very excellent open source ETL tool has been widely used, the general use is the use of client operation management, but the problem is that when used in production environment, hundreds or hundreds of jobs need to be managed, when the use of client management has been very difficult to complete. The solution I know has command-line calls, troublesome operation, in short, it is difficult to use, but also the development of web-side management tools, kettle has a web-side management tool, the interface is extremely simple, not to mention, it is also difficult to use, basically can not be put into production environment, other did not notice there is no better. Tools for managing many jobs.)
