In Java: create unique random filename in a directory

How do I create a random unique filename in a directory (of my choice)?

Note: I don’t want this file in the system temp path but rather in the directory I specify

File.createTempFile() allows you to specify a directory so:

File uniqueFile = File.createTempFile("post", ".html", new File("/var/www/doc"));

You want the File.createTempFile(String, String, File) overload.

Which you would have seen immediately had you bothered to look at the documentation.
