Can someone explain me this
Why course.getVideo() is used here
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.*;
public class QuickFix {
public void addForgottenVideo(Course course) {
List<Video> VideoList = course.getVideo();
Video video = new Video("The Beginning Bits");
VideoList.add(1, video);
}
// TODO(1): Create a new video called "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;
}
}
