Can´t resolve the challenge

I couldn't resolve the challenge, please help me. I am at the second task: Correct the existing hasTile method to return true if the tile is in the tiles field, and false if it isn't. You can solve this a few ways, however, I'd like you to practice returning the result of the expression that uses the index of a char in a String.

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) {
  }
}

What should I do?

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

I have been amazed by how simple the code can be and I wrote it so wrong using an if statement.
