Best way to copy/move files in Java...

Question

I am trying to write or use Java to create directories on the filesystem, based on user information to a servlet. Using the File object and calling the mkdir() method, this works really well. I would like to add the functionality of then moving several files from an existing directory to this new one.
I can certainly write some code that uses the Runtime.getRuntime().exec("cp a.html b.html")and issue a system command, but if there's a better way, I'd appreciate it.
Thanks,
Jay

If you are implying that he use th renameTo() utility
of the File class, then that will only work when the
underlying system allows it - E.G., no renames across
mount points, hard drives, partitions, etc. Copy the
file yourself (with 7 or 8 lines of code) and avoid
the whole thing.I would be willing to accept these restrictions, but I never would have guessed that the renameTo() method would copy the file. That doesn't seem to make sense.
So you think I should just write code that issues a system command. I was hoping to avoid that because I dev and test on my Windows machine, then deploy to Unix. Is there nothing out there that handles file copies?
