Question

How to call the authentication window, to grant access for root for a while for current application, from a class. for example, I\'m writing some app to work with partitions, so

Answer 1

Probably you can't do that with Java. The best way to do is, maybe you can detect that program is not run as sudo so you can ask users to shutdown the program and relaunch as super user. (for this solution, I'd prefer choosing a file or directory from system files and check whether it is writable or not. e.g. new File("/usr/bin/ls").isWritable())

Other ways might be launching Desktop Environment-specific authentication windows. e.g. There is Java-gnome but as you might expect, not all users supposed to use GNOME. So there is not really a universal solution and all comes with tons of dependencies. Java is not designed for this.

The best thing is to check super user privileges with a trick on startup. Maybe you can elaborate your problem and we can come up with a solution that does not require root access.
