I am unsure on how to do this lesson. Can I please have some help.

I am on Java Objects, and I am not sure what is the flaw in my code. Can somebody please help me.

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 Integer getTitleCount() {

    for (char letter : mHand.toCharArray()) {

      int matches += 0;
      if (letter == mHand.indexOf(tile)) {
        return matches += 1;
      }
    }
  }
}

What the challenge wants is a method you can pass a tile to, say 'M', and the method will tell you how many 'M's there are in the player's hand. So you need to have a char parameter for your method.

Then you loop through the player's hand, and each time a tile in the hand matches the tile passed in, you increment count.

   public int getTileCount(char tile){
      int count = 0;
      for (int i = 0; i < mHand.length(); i++) {
         if(mHand.charAt(i) == tile){
            count++; 
         }
      }
      return count;
   }

Note, it has to be a loop, not an if...else..., as the player could have as many as 7 (or 9) tiles.
