Code from p548, had to add a second Jukebox3 class because the book has the...

import java.util.ArrayList;

import java.util.Collections;

public class Jukebox3Works {

    ArrayList<SongV3> mySongs;

    MockSongV2File mockFile = new MockSongV2File();

    public static void main(String[] args) {

        new Jukebox3Works().go();

    }

    public void go() {

        mySongs = mockFile.getSongsV3();

        System.out.println(mySongs);

        Collections.sort(mySongs);

        System.out.println(mySongs);

    }

}

 No newline at end of file

        mySongs.add(new SongV2("50 ways", "simon", "70"));

        return mySongs;

    }

    public ArrayList<SongV3> getSongsV3() {

        ArrayList<SongV3> mySongs = new ArrayList<>();

        mySongs.add(new SongV3("somersault", "zero 7", "50"));

        mySongs.add(new SongV3("cassidy", "grateful dead", "65"));

        mySongs.add(new SongV3("$10", "hitchhiker", "80"));

        mySongs.add(new SongV3("havana", "cabello", "60"));

        mySongs.add(new SongV3("Cassidy", "grateful dead", "65"));

        mySongs.add(new SongV3("50 ways", "simon", "70"));

        return mySongs;
