Standard concise way to copy a file in Java?

It has always bothered me that the only way to copy a file in Java involves opening streams, declaring a buffer, reading in one file, looping through it, and writing it out to the other steam. The web is littered with similar, yet still slightly different implementations of this type of solution.

Is there a better way that stays within the bounds of the Java language (meaning does not involve exec-ing OS specific commands)? Perhaps in some reliable open source utility package, that would at least obscure this underlying implementation and provide a one line solution?

Remove a symlink to a directory

I have a symlink to an important directory. I want to get rid of that symlink, while keeping the directory behind it.

I tried rm and get back rm: cannot remove 'foo'.
I tried rmdir and got back rmdir: failed to remove 'foo': Directory not empty
I then progressed through rm -f, rm -rf and sudo rm -rf

Then I went to find my back-ups.

Is there a way to get rid of the symlink with out throwing away the baby with the bathwater?
