method seems wrong...

what is wrong with my code, and what does it mean it wants me to return my result in expression?

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

  public ScrabblePlayer() {
    tiles = "";
    misses = "";
  }

  public String getTiles() {
    return tiles;
  }

  public void addTile(char tile) {
    // TODO: Add the tile to tiles
      tiles += tile;
  }

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

}

Hi Welsen

Your task in the challenge only required you to return TRUE or FALSE depending on whether the char tile is in the String tiles or not. You can just using your boolean expression as return variable since your method already stated as Boolean right? Here how you should do it:

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

Yes it is true that String method indexOf should return an int type as answer. However, the statement (tiles.indexOf(tile) != -1a0 is like an if statement which will return a boolean type value TRUE if tile is in the tiles and FALSE if it is not.

I hope this will help a little.
