videosbyTitle()

I need help. I am trying to map the name of the video to the videosbyTitle(), I keep getting expected Map to contain 23 but it contained 1.

com/example/model/Course.java
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;
  }

}
com/example/model/Video.java
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;
  }

}

public class QuickFix {

  public void addForgottenVideo(Course course) {
    // TODO(1):  Create a new video called "The Beginning Bits"

     Video newVideo = new Video("The Beginning Bits");
     List<Video> video = course.getVideos();
     video.add(1, newVideo);




    // 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) {
      Map<String, Video> byName = new HashMap<String, Video>();
      //List<Video> video = course.getVideos();
      //Video newVideo = new Video("");
      //video.add(newVideo);
     Video newVideo = new Video("");
      newVideo.getTitle();
      String vName = course.getName();
    byName.put(vName, newVideo);
    byName.get(vName);
    byName.keySet();
