java - How to get full video download from a link? -

i trying download video link, downloads small part of it, can't watched @ all. how download entire video no matter how large file link?

    try {         url url;         byte[] buf;         int byteread, bytewritten = 0;         url = new url(faddress);         outstream = new bufferedoutputstream(new fileoutputstream(destinationdir + "\\" + localfilename));          conn = url.openconnection();         = conn.getinputstream();         buf = new byte[size];         while ((byteread = is.read(buf)) != -1) {             outstream.write(buf, 0, byteread);             bytewritten += byteread;         }     } catch (exception e) {         e.printstacktrace();     } {         try {             is.close();             outstream.close();         } catch (ioexception e) {             e.printstacktrace();         }     } } 

it looks server may redirect other location code doesn't handle. final location can try method (based on: http://www.mkyong.com/java/java-httpurlconnection-follow-redirect-example/):

public static string getfinallocation(string address) throws ioexception{     url url = new url(address);     httpurlconnection conn = (httpurlconnection)url.openconnection();     int status = conn.getresponsecode();     if (status != httpurlconnection.http_ok)      {         if (status == httpurlconnection.http_moved_temp             || status == httpurlconnection.http_moved_perm             || status == httpurlconnection.http_see_other)         {             string newlocation = conn.getheaderfield("location");             return getfinallocation(newlocation);         }     }     return address; } 

now need change

url = new url(faddress); 

to

url = new url(getfinallocation(faddress));
