to read the parcel in. In the constructor that takes a Parcel parameter, add code to set the member variables from the P

not getting by this code

VideoGame.java
public class VideoGame implements Parcelable {

    public String mTitle = "";
    public int mYear = 0;

    public VideoGame() {
        // intentionally blank

    }

    // getters and setters omitted for brevity!

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(mTitle);
        dest.writeInt(mYear);
    }

    public VideoGame(Parcel in) {
        // Task 1 code here!
       mTitle = in.readString();
    }

    public static final Creator<VideoGame> CREATOR = new Creator<VideoGame>() {
        @Override
        public VideoGame createFromParcel(Parcel source) {
            // Task 2 code here!
           mYear = source.readInt();
          mTitle = source.readString();

            return null;
        }

        @Override
        public VideoGame[] newArray(int size) {
            // Task 3 code here!
          mTitle = in.readString();
           mYear = in.readInt();
          // mTitle = size.readString();
         // mYear= size.readInt();
            return new VideoGame[0];
        }
    };
}

You only read from the parcel in the VideoGame constructor that takes a parcel, not in the createFromParcel() or newArray() method:

public VideoGame(Parcel in) {
    // Task 1 code here!
    mTitle = in.readString();
    mYear = in.readInt();
}

Let me know if you have questions on tasks 2 and 3.
