Based on my code, am I doing something wrong? Or is there something I'm missing?

Tried if statements, but they aren't allowed in this challenge. I've even tried adding an answer to the ScrabblePlayer constructor since I don't see any answer which wold allow me to get a return value of true or false.

In addition, when I attempt to index yesHasTile = tiles.indexOf(tile) != -1; I receive a syntax error saying int and char types are incompatible. I don't see any int variable anywhere. I've been working on this from 10 AM this morning until 5:24 PM this afternoon (Eastern Time, USA). I'm beginning to lose my patience.

Thank you in advance for any advice or help with this challenge. :-)

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; // TODO: Add the tile to tiles

  }

  public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    boolean yesHasTile = tiles.indexOf(tile);
    return true;
    return false;
  }

}
