27,748 Points"Looks like u didn't add the new video in the List" compiler prompt the error every time i execute the code plss help.
Below is the question i m solving :-)
Can you please help me with the functions in the QuickFix.java over the next few tasks? I've included other code files for your reference only. I'm going to pass in this course to the addForgottenVideo method. For this task, can you please follow the TODOs in the comments in the method?
package com.example.model;
import java.util.List;
public class Course {
private String mName;
private List<Video> mVideos;
public Course(String name, List<Video> videos) {
mName = name;
mVideos = videos;
}
public String getName() {
return mName;
}
public List<Video> getVideos() {
return mVideos;
}
}
package com.example.model;
public class Video {
private String mTitle;
public Video(String title) {
mTitle = title;
}
public String getTitle() {
return mTitle;
}
public void setTitle(String title) {
mTitle = title;
}
}
import com.example.model.Course;
import com.example.model.Video;
import java.util.Map;
import java.util.List;
import java.util.ArrayList;
public class QuickFix {
List<Video> secondVideo = new ArrayList<Video>();
public void addForgottenVideo(Course course) {
// TODO(1): Create a new video called "The Beginning Bits"
Video newVideo = new Video("The Beginning Bits");
secondVideo.add(newVideo);
Course courseVideo = new Course("secondVideo",secondVideo);
// TODO(2): Add the newly created video to the course videos as the second video.
}
public void fixVideoTitle(Course course, String oldTitle, String newTitle) {
}
public Map<String, Video> videosByTitle(Course course) {
return null;
}
}

My Java is pretty rusty, so I'm not sure how that works. Hope this helps ?

Treehouse Moderator 37,862 PointsNot quite. In your code you posted, you create a new video (
newVideo
) and add it to a a list calledsecondVideo
, which you then add to a new course that you create calledcourseVideo
. Instead, the new video that you create should be added to the video list of the course passed into the method, calledcourse
.
