any character sequence in java use zero based position so the first is 0 then 1,2,.... so for example

char c = "hello".charAt(0); // c = 'h'

h is 0, e is 1 and so on in counting so we extract the first letter by telling it to give us the letter at the position zero (give us the char at the position number)

Yes, in this case, we are checking just for the first letter because one letter for guess that is all we need in this case
