Treehouse Moderator 68,441 PointsI was able to get your code to pass with the following changes:
import com.example.model.Course;
import com.example.model.Video;
import java.util.TreeMap;
import java.util.ArrayList;
import java.util.Map;
public class QuickFix {
public void addForgottenVideo(Course course) {
// TODO(1): Create a new video called "The Beginning Bits"
course.getVideos().add(1, new Video("The Beginning Bits"));
// TODO(2): Add the newly created video to the course videos as the second video.
}
public void fixVideoTitle(Course course, String oldTitle, String newTitle) {
// Combine your two lines to initialize byTitle
Map<String, Video> byTitle = videosByTitle(course);
// Get video from Map
Video video = byTitle.get(oldTitle);
// update title
video.setTitle(newTitle);
}
public Map<String, Video> videosByTitle(Course course) {
Map<String, Video> byTitle = new TreeMap<String, Video>();
for (Video video : course.getVideos()) {
byTitle.put(video.getTitle(),video);
}
return byTitle;
}
}
