Hi Yuri,

The method needs to take a char as a parameter and return an int. A for:each loop can then be used to iterate through the mHand string and count how many instances of that char occur. So, if the player's hand was H E L L O, the method would be called like: getTileCount('L'); and it would return 2, the number of Ls in the hand.

My solution looks like:

  public int getTileCount(char tile){
    int count = 0;
    for (char letter : mHand.toCharArray()) {
      if(letter == tile){
        count++;
      }
    }
   return count;
 }

I hope that makes sense!

Steve.
