如何用JAVA提取文本文档的多个数据（给分贴）

[baohui54882]

这个帖子是给分的，因为一次只能给100分呵呵，分两个帖子给分

[lihan6415151528]

那就接分了！

[zhanggc1001]

我是来接分地！

[FAFA2008]

还是第一次见到如此慷慨的楼主

[忙碌的布谷鸟]

有意思。呵呵～

[jianghuxiaoxiami]

楼主象征性的意思一下吧，浮云啊～～

[baohui54882]

谢谢各位的帮助，我是新手，以后可能还会有问题请教大家
希望以后还能多多帮助小弟，再次谢过！

[link_1029]

呵呵,客气了哦,希望能对你有所帮助.

多读几次啊，或者用多线程对多个不同文件并行读取

啥意思?

这是刚才给一位朋友作的提取logger的方法
思路是首先得到流，然后组成String,最后用StringApi完成功能

不好意思，在另外一个帖子里已经有朋友帮助过我了，我想给他们200分，可我一个帖子只能给100分，所以我开了另外一个帖子给，所以请其他朋友不用回帖了~~
