I've followed this video precisely and cannot understand what this error means, and why Craig did not get the same error.

6,268 PointsHaven't worked with Java in a while, but in your main function you have instantiated an array called "treets", yet when you get to the last line you are trying to pass in "Treets" -> if you change the last line to "Treets.save(treets)" does that allow you to compile?
