What am I doing wrong?

I created a method called getTileCount but apparently I'm doing something wrong...

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;

  public ScrabblePlayer() {
    mHand = "";
  }

  public String getHand() {
   return mHand;
  }

  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;
  }

  int tileCount;

  public int getTileCount() {
    for (char tile : mHand.toCharArray()) {
      if (mHand.indexOf(tile) >= 0) {
        tileCount += 1;
      }
    }
    return tileCount;
  }

}

try

 public int getTileCount(char tileToCheck) {
   int tileCount = 0; 
   for (char tile : mHand.toCharArray()) {
      if (tile== tileToCheck) {
        tileCount += 1;
      }
    }
    return tileCount;
  }

You need to create tileCount inside the method. It also needs to be set to 0 at the beginning of the method. The other thing is that you need to check each individual char against the tileCount. indexOf will always return true because the tile is always in the string. And you need to receive the tile to test against (hence the parameter).
