27,345 Pointsdidn't 'add' the new video to the List
Can't figure out why adding gets me a compiler error....
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"
String forgottenVid = "The Beginning Bits";
// TODO(2): Add the newly created video to the course videos as the second video.
mVideos.add(forgottenVid);
}
public void fixVideoTitle(Course course, String oldTitle, String newTitle) {
}
public Map<String, Video> videosByTitle(Course course) {
return null;
}
}

23,733 PointsFor the first TODO you need to create a new video object, but you're creating a String. Use the constructor of the Video class:
Video video = new Video("The Beginning Bits");
For the second TODO, mVideos is a private member variable of a different class and you don't have access to it. You need to call the getVideos() method on the course passed in. Also, you need to pass in the index to the add() method so that the video will be the the second one in the list:
course.getVideos().add(1, video);
