Java SE (Java Platform, Standard Edition)

Hi,
How to install font in a system using java, provided i know the font file's address. Is there any specific class/method available for this purpose? Copying the file to windows/font directory will work for windows, but I think it wont be generic to all operating system. So is there anyway to install a font using code?

I also want to know how to make the font available only until my application window is open, It must be available to all other external applications like photoshop, word etc., When I close my window it must un-install automatically or be made not available to other applications. Any suggestions? Please do help! Thanks in advance...
