28+
// 线程都执行完以后， 调用listener的notifiedFinished方法， 这样客户端就能收到通知。
29+
// 具体的实现思路：
30+
// 1. 需要调用ConnectionManager的open方法打开连接， 然后通过Connection.getContentLength方法获得文件的长度
31+
// 2. 至少启动3个线程下载， 注意每个线程需要先调用ConnectionManager的open方法
32+
// 然后调用read方法， read方法中有读取文件的开始位置和结束位置的参数， 返回值是byte[]数组
33+
// 3. 把byte数组写入到文件中
34+
// 4. 所有的线程都下载完成以后， 需要调用listener的notifiedFinished方法
35+

// 下面的代码是示例代码， 也就是说只有一个线程， 你需要改造成多线程的。
