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 TODO 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;
public class QuickFix {
public void addForgottenVideo(Course course) {
mTitle video = new TitleVideo("The Beginning Bits");
// TODO(1): Create a new video called "The Beginning Bits"
mVideos.addCourse("second video");
// TODO(2): Add 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;
}
}

Full Stack JavaScript Techdegree Graduate 35,467 PointsHey there Admire,
For the first task you first want to import a list to add this to,
Thank Craig passes in a course as an argument so we can just use that and the get videos method from course
List<Video> = videoList = course.getVideos();
Should do the trick, next we will want to create the Video and give it the title "The Beginning Bits, Craig wants this added in position to, thankfully List.add gives us the option to dictate what index this goes into.
Video video = new Video("The Beginning Bits");
Finally, we need to add this in the second position in the list
videoList.add(1, video);
After everything your code should look like below.
public void addForgottenVideo(Course course) {
List<Video> videoList = course.getVideos();
Video video = new Video("The Beginning Bits");
videoList.add(1, video);
}
Thanks I hope this helps, shout at me if it doesn't.

19,741 PointsIf you could take a look in Course.java, getVideos() return a generic List. That's why you would use List<Video> to call the getVideos().
