如何将文字中的指定文字设置为段首
问题？
如何从一段杂乱无章的Log文件如下：

将log时间找出，并位于段首依次显示出来，方便查看，效果如下效果：

处理方法：
利用Java中字符串处理可以轻松解决此问题。
附代码：
小结：若单是对字符的替换，很简单，各种文字出来工具都有这种功能，但若实现上述功能，估计还得网站下工具了，之前也没搞过这个，不过竟然知道Java中对指定字符串的替换，实现这个功能就显得简单了，只要找到对应的字符串，然后在其前面加上回车换行符号“\r\n”(windows下)，“\n”(linux下)就Ok了。不过我在实现过程中出了点问题，忘了加flush();写入生成的文件为空，以后记得write方法和flush方法是铁哥们，形影不离。
