I don't understand why, and from where, the object "course" is used on this line of the code.
The code line
course.getVideos().add(1, newVideo);
The entire code
import com.example.model.Course;
import com.example.model.Video;
import java.util.Map;
public class QuickFix {
public void addForgottenVideo(Course course) {
// TODO(1): Create a new video called "The Beginning Bits"
Video newVideo = new Video("The Beginning Bits");
// TODO(2): Add the newly created video to the course videos as the second video.
course.getVideos().add(1, newVideo);
}
public void fixVideoTitle(Course course, String oldTitle, String newTitle) {
}
public Map<String, Video> videosByTitle(Course course) {
return null;
}
}
