This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
I'll give you some hints to help you figure this out yourself.
1. What type of object is System.out? (Look it up in the API documentation of class java.lang.System).
2. Look at the API documentation of that class; lookup the println() method.
3. What did you find when you looked up the println() method? Can you now answer your own question?
