Java Java Objects Creating the MVP Scrabble Tiles

Can't seem to solve the problem of checking wether tile exists in tiles

Okay, I tried using a for loop first and that gives me error. Then I tried using indexOf method of strings and that gives me error as well. What's going wrong in these two codes?

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
   /* for (int i=0;i<tile.length();i++) {
      if (tiles.charAt(i)==tile) {
        return true;

    return false;
    return (tiles.indexOf(tile)!=-1);

I have just wrote same code as you and it works perfectly fine. Try refreshing the page. Sometimes it needs refreshing to work.

return (tiles.indexOf(tile)!=-1); // This works fine
