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!

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(char tile)
  {
    int count = 0 ;
    for(char letter:mHand.toCharArray())
    {
      if(mHand.indexOf(tile)>=0)
      {
        count=count+1;
      }
    }

    return count;
  }
}

Let's think through your code a bit here....

// For each letter in the hand
for(char letter:mHand.toCharArray()) {
   // If the hand has the tile that was passed into the function...
   if(mHand.indexOf(tile)>=0) {
      // Increment the count
      count++;

HINT: Why not see if each letter is actually the tile. (use ==)
