public TYPE getTileCount(ARGUMENT); {
    for (char ITERATOR: mHand.toCharArray()) { 
      if(EXPRESSION) {

    }
  }

The problem is this method. You need to change TYPE, ARGUMENT, EXPRESSION. You dont have to change the word ITERATOR, but you probably should.

  1. The 'TYPE' is the return type for this method, probably an int
  2. The 'ARGUMENT' is the variable that accept input into the method.
  3. The 'EXPRESSION' should check if the 'ITERATOR' is equal to the char passed in as an argument
  4. You are missing one closing bracket.
  5. Right after the argument parenthesis you have a semi-colon, that shouldn't be there.

I think this should get you started, Let me know if you need anything else.
