16,212 Pointstotally use that videosByTitle
I dont get what I am missing here... help please :)
It is the final step, but keeps saying that it does not recognise the videosByTitle method that I just defined...
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.HashMap;
import java.util.List;
public class QuickFix {
public void addForgottenVideo(Course course) {
Video video = new Video ("The beginning Bits");
List<Video> videoList = course.getVideos();
videoList.add(1, video);
}
public void fixVideoTitle(Course course, String oldTitle, String newTitle) {
Map<String, Video> videos = videosBytitle(course);
Video video = videos.get(oldTitle);
video.setTitle(newTitle);
}
public Map<String, Video> videosByTitle(Course course) {
Map<String, Video> titleToVideo = new HashMap<>();
List<Video> videos = course.getVideos();
for (Video video: videos) {
titleToVideo.put(video.getTitle(), video);
}
return titleToVideo;
}
}

My code looks similar:
public Map<String, Video> videosByTitle(Course course) {
HashMap videoMap = new HashMap<String, Video>();
for(Video video : course.getVideos()){
videoMap.put(video.getTitle(), video);
}
return videoMap;
}
What you've not done is import the HashMap
! Just add that and your code works fine.
Steve.
