java读取txt文件，提取目录为html文件

2013-08-20 00:00 155 查看

（文中的代码源于链接：http://blog.csdn.net/inowcome/article/details/6047661，但自己运行时稍有问题，做了修改。）

代码功能：java读取txt文件的小应用，将txt文件里面的章节信息提取出来，生成一个动态链接的html文档。该代码源于网络，自己加以修改。给出核心的内容：

/*
* 用来将只放在一个文件中的小说切隔成
* 一个章节的html页面，其中每个页面还包括上一页，下一页，目录的超链接
* 同时还生成一个目录文件contents.html
*====================
*注意源码的编码是：utf-8
*文件读取的来源文件的编码也需是utf-8
*===================
*这里的神墓的切隔的原理是：
*根据第一个章节的标题都包含："章 "
*
