[Ch10c] test for sorting by least played. We were right, this is a horrible example for streams.

    List<Log> log = new Log().getLog();

  private JukeboxData.Songs songs;

  private List<Log> log;

    System.out.println(log);

  @BeforeEach

  void setUp() {

    songs = new JukeboxData.Songs();

    log = new Log().getLog();

  }

    List<Song> allSongs = log.stream().map(log1 -> songs.getSongById(log1.id))

  @Test

  void shouldOutputAllSongsPlayed() {

    List<Song> allSongs = log.stream()

                             .map(logEntry -> songs.getSongById(logEntry.id))

                             .collect(Collectors.toList());

    System.out.println(allSongs);

  }

  @Test

  void shouldOrderByLeastPlayed() {

    // this is impossible!!!!

    // back to square one

//    List<Song> result = log.stream()

//                           .map(logEntry -> songs.getSongById(logEntry.id))

//            .sorted(Comparator.comparingInt())

//                           .collect(Collectors.toList());
