downloading a large file in java

Question

here is my code for downloading a file from a webpage and saving it in a path:

import java.io.File;
import java.io.IOException;
import java.net.URL;

import org.apache.commons.io.FileUtils;

public class Demo2 {
    public static void main(String...args){

        try {
            URL url = new URL("ftp://ftp.fu-berlin.de/pub/misc/movies/database/crazy-credits.list.gz");
            FileUtils.copyURLToFile(url, new File("D:\\imdb\\credits.list.gz"));
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

I'm getting a connection timed out exception:

java.net.ConnectException: Connection timed out: connect

I'm unable to figure out what exactly is the issue as it works fine for other urls like:

http://www.vtuplanet.com/d.php?type=papers&file=B.E+%28Engineering%29%2FComputer+Science+%28CSE%29%2FSem+5%2FDBMS%2FDBMS+Notes+%5B2010%5D+%28SJBIT%29.pdf

Can someone please help me with this? thanks in advance!!

Well it sounds like the connection to ftp.fu-berlin.de has timed out, given the error message... are you able to download that URL with a browser? — Jon Skeet, Jul 05 '16 at 09:10
check below link and try to do it asynchronously http://stackoverflow.com/questions/921262/how-to-download-and-save-a-file-from-internet-using-java — Chirag Arora, Jul 05 '16 at 09:12
The FTP port at that location is not open in its firewall. Nothing you can do about it from the client end. @ChiragArora Async I/O won't solve this problem. You can't even do async I/O if you can't create a connection. — user207421, Jul 05 '16 at 09:15
@Jon Skeet yes i am able to download that that URL with a browser — khalibali, Jul 05 '16 at 09:20
The code works fine for me. It's probably something with the network configuration. — Jan B., Jul 05 '16 at 09:36
I can download file with your code. Check your network firewall — Kaliappan, Jul 05 '16 at 09:45
