这就是 Pascal 语言的设计者 Niklaus Wirth 将其著作命名为《算法 + 数据结构 = 程序》(Algorithms + Data Structures = Programs, Prentice Hall, 1975 )的原因。需要注意的是,在 Wirth 命名的书名中, 算法是第一位的,数据结构是第二位的,这就明确地表述了程序员的 工作方式。先要确定如何操作数据, 然后再...

To gain this scalable performance, programmers must rewrite existing programs to use new libraries [5]. Manual rewriting is labor intensive because many program fragments must be modi- fied consistently across all of the source files. This work is error- prone, because the programmer cannot easily...
1.1.2 Programs before the web Before the World Wide Web, programs were generated differently according to system on which they were intended to run: a program running on a Macintosh computer could not be used with another computer with a different operating system – the program that controls ...

基于Java的通用PDF文档生成开源软件的开发主要以 JavaGUI、iText,jCom等Java插件为开发环境,采用 openOffice和虚拟adobePDF打印机作为后台支持进程软件。 本软件采用iText制作PDF文档和jCom转化文档技术,以 openOffice作为后台支持程序开发研制一款绿色开源软件。
java可以直接调用这个类实现画图功能,但是使用这个类的前提是你的电脑已经装了GraphViz软件,你可以在http://www.graphviz.org/Gallery.php下载windows版本,装完后,找到dot.exe所在的路径,我电脑上的是D:\Program Files\Graphviz2.30\bin\dot.exe,将GraphViz.java中的这一路径改成你电脑上的路径,基本上就可以用了。
