So, I know this question could turn out to be pretty dumb, or that I may have missed the explanation earlier on in the course/lesson, but:
(Disclaimer: My code is written just like Craig's and works perfectly, soI am not questioning the results, nor am I troubleshooting why it won't run.)
This part of the code is confusing me:
public String getCurrentProgress() { String progress = ""; for (char letter : answer.toCharArray()) { char display = '_'; if (hits.indexOf(letter) != -1) { display = letter; } progress += display; } return progress; }
Shouldn't this mean that the character "letter" (e.g. "t") will be compared to the content of the "hits" string for as many times as there are characters in the "answer" string (e.g. "treehouse" - i.e. 9 times)?
Also, in this case, since "t" is a hit, why doesn't the code then add "t" to the "progress" string 9 times, resulting in the string essentially turning into "ttttttttt"?
Am I missing something here? Any feedback is appreciated. :)

Full Stack JavaScript Techdegree Student 18,029 Pointswhen a char array is made, it breaks up a string into what is essentially its parts like so: Pancakes.toCharArray() would be P-a-n-c-a-k-e-s. The for each loop will just move from "P" then to "a" then to "n" and so on until it reaches the end. At each char, the if statement evaluates to see if the letter present is in fact a letter at all. Which in your case is represented by making sure it is !=-1 this is the value of a blank space.
so the same letter is not displayed over and over, rather if the "t" index in the array is a letter and not a blank spot the progress string will add "t" to its list of stored values and move on to evaluate the next char in the same fashion until it runs out of chars to evaluate then it will return the string called progress

4,662 PointsThanks! This makes sense. I'm still not entirely clear on how a lot of stuff works in Java (and sometimes googling doesn't really help.).
P.S. After I posted the question, I realized that it was in no way tied to the lesson I was following, but I don't know how to do that. :( Nor do I know how to paste the code in a way that it's different than the rest of the text (i.e. colorized and with a black background).
