6种字符串数组的java排序 (String array sort)注意，本文不是字符串排序，是字符串数组的排序。方法分别是：1、低位优先键索引排序2、高位优先建索引排序3、Java自带排序（经过调优的归并排序）4、冒泡排序5、快速排序6、三向快速排序时间复杂度：最慢的肯定是冒泡，O(n的平方)...

项目需要将音视频文件上传服务器，考虑并发要求高，通过七牛来实现。做了一个简易的压力测试，同时上传多个文件，七牛自己应该有队列处理并发请求，我无论同时提交多少个文件，七牛是批量一个个排队处理了。一个1.5MB的文件，上传时间大概2-3秒，感觉不错。  直接上代码 using Qiniu.IO;using Qiniu.IO.Resumable;using Qin
