My Java code:

con = (HttpURLConnection) obj.openConnection();

con.setInstanceFollowRedirects(false);

con.setRequestProperty("X-Direct-Download", "true");

con.setRequestMethod("GET");

con.setRequestProperty("Accept-Language", "en-US,en;q=0.5");

Output File is Creating Now

responseCode:302

---------------------------------------------

Somehow getting 302 response code but its not downloading the file with streams. Here is my code which downloads file. (Link printed in logs is downloadable though)

DataInputStream readerIS = new DataInputStream(con.getInputStream());

Files.copy (readerIS, Paths.get (fileName), StandardCopyOption.REPLACE_EXISTING);

Please suggest what else is needed here.
