Help

I do understand we need the "return applyGuess" what I don't understand is why we need the "(letters.charAt(0))".

The letters variable represents the input from the user. It is of type String. Because we are accepting the input as a String the user could input "you know nothing John Snow", but are only concerned with the first letter of the String. Strings are 0 indexed so to get the first letter of any String charAt(0). 

return applyGuess(letters.charAt(0));
// This gets the first character of the letters variable, 
// 'y' in the above user input 
// sends that character to the applyGuess() method
// and returns the boolean if it was added
