Getting A File's Mime Type In Java

Question

I was just wondering how most people fetch a mime type from a file in Java? So far I\'ve tried two utils: JMimeMagic & Mime-Util.

Answer 1

I tried several ways to do it, including the first ones said by @Joshua Fox. But some don't recognize frequent mimetypes like for PDF files, and other could not be trustable with fake files (I tried with a RAR file with extension changed to TIF). The solution I found, as also is said by @Joshua Fox in a superficial way, is to use MimeUtil2, like this:

MimeUtil2 mimeUtil = new MimeUtil2();
mimeUtil.registerMimeDetector("eu.medsea.mimeutil.detector.MagicMimeMimeDetector");
String mimeType = MimeUtil2.getMostSpecificMimeType(mimeUtil.getMimeTypes(file)).toString();
