Getting error that says to use the method reference to get the player. Don't know what that means.

com.teamtreehouse.challenges.highscores.MainTest > mapIsUsedWithMethodReference FAILED java.lang.AssertionError: Please make use of the method reference in your 'getFirstFiveAmazingPlayersDeclaratively' method to get the player at org.junit.Assert.fail(Assert.java:88) at org.junit.Assert.assertTrue(Assert.java:41) at com.teamtreehouse.challenges.highscores.MainTest.mapIsUsedWithMethodReference(MainTest.java:82)

code:

 public static List<String> getFirstFiveAmazingPlayersDeclaratively(List<Score> scores) {
    // TODO: Filter where amount is greater than 100,000
    // TODO: Map to the player's name
    // TODO: Limit to 5
    // TODO: And collect those strings and return them
    return scores.stream()
      .filter(score -> score.getAmount() > 100000)
      .map(Main::getScorePlayers)
      .limit(5)
      .collect(Collectors.toList());

  }

  public static String getScorePlayers(Score score) {

    String player = score.getPlayer();

    return player;

  }

You should use .map(Score::getPlayer) instead of .map(Main::getScorePlayers) in stream chain.
