Treehouse TeacherHi Emily!
This line
videoList = course.getVideos();
is missing a declaration. What type is videoList? Not sure you need it, you can use course.getVideos()
in your for loop.
This line
Map<String, Video> videosByTitle(Course course) {
Looks like an accidental re-declaration of the method inside the method. Whoops!
You're populating of the map looks great!
