Confused at the challenge question

hello,

This may sound strange but i've never played scrabble before in my life and I'm very confused at what the question is asking me to do. I've looked up how to play scrabble but it doesn't really help. Can someone give me a pointer on this please?

Thank you.

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;
  }
}

This is my current attempt but its not accepting

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

Because you are being asked to count the number of tiles that match a particular letter, you'll need to pass that letter to the method as a char argument. Then in the for loop as it goes through each tile of the hand, you'll need to compare that letter to the current tile
