突然想做一个类似KDE管理中心那样的gnome的配置管理器，来集中的管理gnome或其他图形管理环境下系统的配置。而众所周知，linux的底层配置多是用各种配置文件来保存信息的，有早期的::分割格式的，有新的xml分割的，还有一些特殊脚本形式的。其中尚有一些是采用的类似windows
ini配置文件格式的。
不知道是我固陋寡闻还是真的就没有，java
api里居然没有ini读写操作支持，查找一些文章，有的说什么Properties能操作ini，但我发现它好像是一个操作xml配置文件的类，总之不管如何，有也好没也好，ini文件结构并不复杂，自己写了一个完整的工具类，就当好久没弄java了练练手吧。
一下转入正题：
思路：ini配置文件-->数组-->ArrayList1-->清理代码（单行分析，先区分空行，注释行，替换为注释符，去掉首尾空格=两侧空格）-->ArrayList2(此后的读操作用2，写操作到1）-->查找类别-->查找变量-->得到值[-->改写值-->myWriter()写入文件]
（恕我不善言词，直接贴出代码）
