It doesnt ask to provide a argument in the method, but the hint suggests i need to add a char

What am I am missing here, the hint is saying if i forgot to add a char as an argument to the method but it never specified to add one. PLEASE HELP!!!

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;
  }

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

The method must accept a char as a parameter. Next, it should check if the char passed in is somewhere in mHand! You're close, so you'll definitely figure it out on your own in no time!
