File movement and copying

Question

Here where i work we use a software, whose files are stored on the server. But we also have a local copy of these files so that we can use the software when not in the office. Or when the server is down. The problem is, that many of my co workers are not very computer literate and the constant copying back and forth of files confuses them.
So I am trying to write an updater application. Basically all they would have to do is click a button, it would tell them whether there had been any important changes, and allow them to update by pressing a single other button.
I have the gui written, I have all the checks done, but i cannot figure out how to make Java take files in one place and copy them to another place. I would think this would be something that java is capable of. But as of this moment I am drawing a blank.
Any ideas?

Answer 1

Quick and dirty method is to use Runtime.exec() to execute the copy/move commands directly, though this is platform dependant.
Another way is to use InputStream and OutputStream to read the original file and write out the copy of the file.
