I have completed the prework for this SB, but when I check the first challenge, I am told that I did not create a constant with the immutable property. To my knowledge, there IS no immutable property on a constant. I created the Constants class with the required constants, all with the static and final keywords. Could someone explain why I am getting the error message?
