For some reason when I try to use the "clear" command just to keep up with him in this here video, I get an error message stating "not a statement".
Anyone know why this is?

Courses Plus Student 26,868 PointsHi, Justin Butler , actually during the video, Craig also mentioned that, as soon as he typed :cls, the Java REPL was crashed, that's why it got sent back to the workspace command line.
Now, if you type :cls and it does what it does, clearing up the Java REPL screen instead of crashing Java REPL, that's great, because that means the Java REPL is updated to have one less crashing bug, and becomes more stable.

10,331 Pointsyou mean like ":cls"?

Courses Plus Student 26,868 Pointsyeah, :cls should work within Java REPL
but if you want to use the clear command, you have to exit the JAVA REPL and back to the console in order to use it, as this clear command is available in the native Console only.

You can tell if you're in the java-repl as your prompt will say java> rather than just something like treehouse:~/workspace$
