**In the video, Craig created a Class named SongBook. In the class it had a private variable list of Song named mSongs and a constructor :
private List<Song> mSongs;
public SongBook() { mSongs = new ArrayList<Song>(); }
**Was it really necessary to create the constructor in this situation? Why didn't he keep it simple and did this instead:
private List<song> mSongs = new ArrayList<Song>();
