Can someone check whether I am understanding the question

" So back to that ScrabblePlayer. I found that it's not enough to know if they just have a tile of a specific character. We need to know how many they actually have. Can you please add a method called getTileCount that uses the for each loop you just learned to loop through the characters and increment a counter if it matches? Return the count, please, thanks!"

So...are we looping through the characters of mHand and then adding 1 to count if there are two of the same character?

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;
  }
}

Hey Donna,

You are mostly correct, what they want the challenge to do is loop through each tile in the hand, and mark how much of each tile they have, so they don't need to be repeating, say that we have the file abcdefg it will go through each tile, and when it finds a it will increment the counter of a by 1, and same with each tile, In the event you had aabcdef it would see a twice, so it return a value of 2 for a, and 1 for each of the other chars in the hand, and 0 for all of that are not present.
