Using both IntelliJ and NetBeans import java.io.Console; Console console = System.console(); console = console.printf("Hello TreeHouse");

I got Null pointer exceptions, where as: changed to System.out.println("Hello my Name is ...") ; within the IDEs were able to produce a console output within the IDE console.

I'm getting this on the workspace used in the "feeling loopy with java" workshop. I was able to run my programs fine as recently as early yesterday, but now they aren't working.
