It's telling me counter is returning 1 when it should be returning 0

I don't see why it should be returning 1 if n is inputed and n is not one of the 8 tiles of the hand. I cannot find an error in my code help would be appreciated.

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;
  public int counter = 0;
  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;
  }

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

Try putting the counter variable inside method instead of as a public variable.

Craig, I appreciate the help it worked! I am still confused though because in reality shouldn't the code as I had it work? I figure that as long as nothing else modifies the counter value besides the if conditional, making it a 'public int' should work. Also, if I had just declared the counter variable by typing 'public int counter;' at the top, what does java set the integer to initially? 0? Blank space?
