Error :
./QuickFix.java:12: error: cannot find symbol course.add(1, video); ^ symbol: method add(int,Video) location: variable course of type Course 1 error
I don't see what the problem is because that is how you add to a list on a specific spot. So what is the problem?
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;
public class QuickFix {
public void addForgottenVideo(Course course) {
// TODO(1): Create a new video called "The Beginning Bits"
Video video = new Video("The Beginning Bits");
// TODO(2): Add the newly created video to the course videos as the second video.
course.add(1, video);
}
public void fixVideoTitle(Course course, String oldTitle, String newTitle) {
}
public Map<String, Video> videosByTitle(Course course) {
return null;
}
}

4,902 PointsHi Kenneth, try importing the list at the beginning of the method 'addForgottenVideo' that Craig made for you.
That way you have a list to add it, right now I believe you are not using any list.
Edit: sorry, you can't add a video to a 'course' list, you need to add it to a videoList, fix that also:
videoList.add(1,video);
PS: don't forget your imports:
import java.util.List;
Have a great day.
