It’s probably easy to send all System.out.print’s to the Null-device but I can’t remember how…
You’ve to use System.setOut(…) but with what parameter, please?
Btw. is it a bad idea to do this? Critical (=usually application error) messages I always print to the err stream instead of out. All the System.out’s are just verbose but I’d like to avoid them if a parameter is being set…
