scrabble part 2 unsure how to make the code pass

Unsure about this task. Also unsure of the why behind it.

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) {
    // TODO: Add the tile to tiles

    tiles += tile;

  }

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

}

Hi Ian Whitney

Thanks for attempting this challenge, this is how we learn

So all you need to do is to loop through character or letters on tiles using for-loop . You can use toCharArray().length method to establish the number/length of tiles array although we obviously know it to be seven tiles.

Next is the String's indexOf() method which returns 0 or number greater than 0 if the letter matches letters on the tiles. So the code will loop through the tiles and return true if letters match.

Please see my code below;

public boolean hasTile(char tile) {

   for( int i = 0; i < tiles.toCharArray().length; i++  ){
     return ( tiles.indexOf(tile) >= 0);
   }

    return false;
  }

Hope this helps.
