Welcome to the Treehouse Community
Looking to learn something new?
In the video he "saves" the code, but I do not follow how it is "saved"
I cannot add onto the code, "Hello, my name is Craig. Craig is learning to write Java."
In most editors you can save your code to the associated file with either a menu item, typically located under the 'file' menu, or with a keyboard shortcut. On a Mac that shortcut would be Command-s and on Windows it would be Control-s.
