40,533 PointsYou'll need to update your imports to help the compiler find the definitions:
import java.util.List;
import java.util.ArrayList;
Then you'll want to change how you're creating the updated list. Since you're adding a video to the course's list you'll want to grab that collection instead of creating a new one:
// Get the videos from the course passed in
List<Video> videoList = course.getVideos();
