Java Java Objects Creating the MVP Scrabble Tiles

What am i missing here?

public boolean addTile(char tile) { boolean isTile = tiles.indexOf(tile) != -1; if (isTile) { tile += tiles; } return isTile; }

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 boolean addTile(char tile) {
         boolean isTile = tiles.indexOf(tile) != -1;
         if (isTile) {
         tile += tiles;
    }
    return isTile;
  }
}
  public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    return false;
  }
}

addTile() is just to add the tile to the players existing tiles. Remove the boolean from the method and add void since it isn't returning anything, it should look like this:

The hasTile() method is where you return the boolean value. The challenge asks that you complete it without an "if" statement as well. Just return it all in one. it will return true if the player has it already. :)

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) {
        tile += tiles;
 }
  public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    return (tiles.indexOf(tile) > 0);
  }
}
