Here the code that has worked for me:
import com.example.model.Course;
import com.example.model.Video;
import java.util.Map;
import java.util.TreeMap;
public class QuickFix {
public void addForgottenVideo(Course course) {
// TODO(1): Create a new video called "The Beginning Bits"
Video vid = new Video("The Beginning Bits");
// TODO(2): Add the newly created video to the course videos as the second video.
course.getVideos().add(1, vid);
}
public void fixVideoTitle(Course course, String oldTitle, String newTitle) {
Map<String, Video> oldTitleVideoMap = videosByTitle(course);
Video vid = oldTitleVideoMap.get(oldTitle);
vid.setTitle(newTitle);
}
public Map<String, Video> videosByTitle(Course course) {
Map<String, Video> mapVideos = new TreeMap<String, Video>();
for (Video video : course.getVideos()) {
mapVideos.put(video.getTitle(), video);
}
return mapVideos;
}
}
