将java源文件生成html并且高亮彩色显示

摘要: 将java源文件生成html并且高亮彩色显示

</td> </tr> <tr> <td height="35" valign="top" class="ArticleTeitle"> <table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <td height="42" align="left" valign="top"> </td> </tr> </table> 下面程序能将java源代码生成html文件并且高亮彩色显示,点击这里可以观看效果。

运行方法：只要在命令行输入java源文件名和生成的html文件名。
如：

C:\java>java java2html GetURL.java ds1.html
成功生成ds1.html文件

下面是这个程序的源码：
