2,350 PointsI cannot make this Map method
I cannot solve this problem that is in QuickFix.java and method videosByTitle(). It is aching me! I tried this but it threw that I have a bug ... Error Message: Expected map to contain 23 keys but it contained 1.
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"
// TODO(2): Add the newly created video to the course videos as the second video.
Video video = new Video("The Beginning Bits");
course.getVideos().add(1, video);
}
public void fixVideoTitle(Course course, String oldTitle, String newTitle) {
}
public Map<String, Video> videosByTitle(Course course) {
public Map<String, Video> videosByTitle(Course course) {
Map<String, Video> officialCourse = new HashMap<String,Video>();
for (Video videos : course.getVideos()) {
officialCourse.put(course.getName(), videos);
}
return officialCourse;
}
}

16,266 PointsTry to follow these steps -
- The
Course
object passed in to thevideosByTitlemethod
has a getter that will return aList
of videos. - Create a new
Map
object invideosByTitle
method. - For each video in the list of videos returned from step 1, add to the map object - the title of the video, and the video itself.
- Return the map object.
That should work.
