Sounds like you want to look into threads and the java.net.URL class.
First, though, you should make sure you have a solid grounding in the
language itself.

I suspect that would not get you the file any faster. You use
multiple streams to download multiple files.
There is a single stream download utility part of the FileTransfer
classes. See http://mindprod.com/products1.html#FILETRANSFER.

Then modify that to allow download of a chunk of the file. then add
your threads. Read up on http protocol. See
