// 在这里实现你的代码， 注意： 需要用多线程实现下载
32+
// 这个类依赖于其他几个接口, 你需要写这几个接口的实现代码
33+
// (1) ConnectionManager , 可以打开一个连接，通过Connection可以读取其中的一段（用startPos, endPos来指定）
34+
// (2) DownloadListener, 由于是多线程下载， 调用这个类的客户端不知道什么时候结束，所以你需要实现当所有
35+
// 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。
36+
// 具体的实现思路：
37+
// 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
38+
// 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
39+
// 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
40+
// 3. 把byte数组写入到文件中
41+
// 4. 所有的线程都下载完成以后， 需要调用listener的notifiedFinished方法
42+
43+
// 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。
