That's definitely a legacy approach.  It's really against the spirit of Java to be calling directly to the OS to do something very simple like file copying.

You are much better to use the Files.copy() method.

The one using the Runtime will only work on Linux (or more generally an OS that has a built in "cp" command that is on the path) and any errors from that method will be very hard to handle correctly.

So take it out and put in your new code.
