Learning Java with JShell in NetBeans IDE

Sweet documentation explains everything:

Next, let's put that useful code snippet to some use... i.e., we'll move it into a new Java source file in my application:

And there it is, all the verbosity/expressiveness of Java wrapped around our little snippet:

Hmmm. This will be pretty useful for anyone teaching and/or learning Java.

    Great stuff, Geertjan, but you forgot to mention WHERE this is available. You are not talking about current NetBeans are you?

    I may be missing something but it looks like the output is shown in a new window. Why don't you show the output inside the shell? I think having the output inside the shell is more natural.
