Yes you can - use FilePermission of the java.io package. You can set read,
write, execute and delete permission separately or all at once by passing
the appropriate string to the constructor. But your question seems to more
oriented around ownership of the files. I don't know of a way (except maybe
through an exec, but that limits your code to a particular platform) to do
the equivalent of chown in Unix with Java.
Cheers!
