5,225 PointsI don't know how to add the new video to the list of course videos
I think I created the new video "The Beginning Bits" correctly but I'm not sure how to add it to the list of course videos.
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 theBeginningBits = new Video("The Beginning Bits");
// 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;
}
}

15,193 PointsBummer! Looks like you didn't 'add' the new video to the List
They clearly want you to use the '.add' method. We can't just do this on 'course', we have to do it on a list of videos. Thankfully they gave us a method in Course.java to get that list.
public List<Video> getVideos() {
return mVideos;
}
Now it is just a matter of adding it to the second position.
course.getVideos().add(1, theBeginningBits); //<-------add your video object to the position 1
Here is your final code
public void addForgottenVideo(Course course) {
// TODO(1): Create a new video called "The Beginning Bits"
Video theBeginningBits = new Video("The Beginning Bits");
// TODO(2): Add the newly created video to the course videos as the second video.
course.getVideos().add(1, theBeginningBits);
}

Please try this, mind to screen, not tested ... but give it a try:
// TODO(2): Add the newly created video to the course videos as the second video.
course.getVideos().add(theBeginningBits);
if this answers your question, please mark the question as answered.
