Question

I am creating an Application in Java that does parsing of HTML and get all the <audio>, <img> and <video> tags. I did this using jsoup. I have the attribute href, and therefore I get the link, I want a way to download the file to my PC through the tag. Is that possible through Java?

I saw a common format is ftp://user:password@host:port/filePath;type=i. but I dont know FTP for sites then how i can download the images and links.

Answer 1

First just get the absolute URL from the href attribute in Jsoup using Node#absUrl().

String absUrl = element.absUrl("href");

Then you can get an InputStream out of it using URL#openStream().

InputStream input = new URL(absUrl).openStream();

Then you can write it to an arbitrary OutputStream the usual way. E.g. to a FileOutputStream.

OutputStream output = new FileOutputStream(somepath);
// Just write input to output the usual way.

Note that this all has nothing to do with FTP. That’s a completely different subject.
