Help needed with Scrabble game

Hi.

Can anyone please tell me what's wrong with this:

  public String getTileCount() {
    String letter = "";
    for (char tilesForLetter: mHand.toLetterNumber()) {
      char display = '-';
      if (mHand.indexOf(tilesForLetter) == 0) {
        display = tilesForLetter;
      }
    }
  }

Thanks.

Sean :-)

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;

  public ScrabblePlayer() {
    mHand = "";
  }

  public String getHand() {
   return mHand;
  }

  public String getTileCount() {
    String letter = "";
    for (char tilesForLetter: mHand.toLetterNumber()) {
      char display = '-';
      if (mHand.indexOf(tilesForLetter) == 0) {
        display = tilesForLetter;
      }
    }
  }

  public void addTile(char tile) {
    // Adds the tile to the hand of the player
    mHand += tile;
  }

  public boolean hasTile(char tile) {
   return mHand.indexOf(tile) > -1;
  }
}

//The return type should be int because you're asked to return a count of how many tiles of this type you have.
  public int getTileCount(char tile) {
//The method takes a tile as a paremeter.That is the tile you need to check if you have it.
    int count = 0;
//We initialize the count here.
    for (char tilesForLetter: mHand.toCharArray()) {
//We use a for each loop.
//mHand.toCharArray() changes mHand to a array of characters.
      if (tile == tilesForLetter) {
        count++;
//If the tile which is the parameter is equal to one of the tiles in the hand we increment the count.
      }
    }
  return count;
}
