Since you make a call to your hasTile() method, let me first explain this: this method checks to see if the char passed in is present in the mHand variable. The getTileCount() method checks to see HOW MANY of those tiles are present in mHand.

So in the getTileCount() method, the Char testCharacter parameter you pass in will be tested to see how many times it shows up in our mHand. The only changes you need to make is inside your if condition. We don't need to make a call to hasTile, instead, we're checking to see if each letter in the charArray (represented by the variable c) is equal to the parameter we pass in, so your conditional statement will look like this:

if (c == testCharacter)
