i think the error you get is quite descriptive: TimeLine.java:18: error ‘{’ expected

it tells you what is missing, as well where you forgot the curly bracket.


follow op question to this screenshot. I get this error a lot, but codeacademy still excepts the solution, just as you see there. What is up with that? Also I don’t see how you can tell from this error where curly brackets are missing.
