接口的方法能不能少一点？简单点？

某个接口的设计

FileConnector 

public void saveFile(String uploadPath, File[] files)
   throws FileNotFoundException;

为什么是File[]？很奇怪，考虑复杂业务是不是太多了？实现类受得了这么折腾吗？

 //XXX: 能否就指定文件的path？
 public void saveFile(String uploadPath, String fileName,
   InputStream inputStream) throws FileNotFoundException;

最后改成：

 <T> T read(InputStreamReader<T> reader) throws IOException;

 void write(OutputStreamWriter writer) throws IOException;
