Question

In my app, I have to present a few numbers from a .csv file that’s accessible from the web. Now, this .csv is quite big. I don’t want to download and process the whole thing, there’s no point. My numbers are always in the beginning of the file, in well specified positions – lets say position 5 to 10.

Could you give me some tips on how to implement this? I know how to download the whole thing, but don’t know how to download only a part of it.

Thanks.

Psuedo:

BufferedReader br = new BufferedReader (new InputStreamReader(remoteStream));
String sFirstLine = br.readLine();

remoteStream is the stream of the connection to the remote server. Getting a handle to the stream is not the same as actually downloading. Only the BufferedReader.readLine() actually downloads anything
