> how do we use range header in java?
The same as any other header. However, I have my doubts if the old
HttpURLConnection class in Java will be able to deal with all the finer
details of HTTP/1.1 ranges. You might consider investigating the Apache
Jakarta Commons library.

It isn't. It is a GET with range headers. If you don't know what headers
in HTTP are, see the above mentioned reference.
