I am having trouble understanding what needs to be done to when it says try returning the results of the expression.

I am currently returning true if the character that is being pushed in from hasTile is in the current hand and I am returning false if it is not. Not sure why this is not working but the challenge says "Try returning the results of the expression". Which I am a bit confused about.

ScrabblePlayer.java 
public class ScrabblePlayer {
  // A String representing all of the tiles that this player has
  private String tiles;

  public ScrabblePlayer() {
    tiles = "";
  }

  public String getTiles() {
    return tiles;
  }

  public void addTile(char tile) {
    tiles += tile;

  }

  public boolean hasTile(char tile) {
    boolean currentHand = tiles.indexOf(tile) != -1;
    if (currentHand) {
      return true;
    } else {
      return false;
    }

  }

}

it is telling you to ditch the if statement block and just return the conditional statement, ie if you were to put return 1 > 2, the return value would be false. there is no need to say if true, return true, if false, return false like you have. the statement will be evaluated and whatever it is will be the return value.

Thanks James! That helped a lot. I removed the if statement and added "return currentHand;" after "boolean currentHand = tiles.indexOf(tile) != -1;" and it worked! Is that what you had in mind? Or is that still redundant?
