Answer 1

Oh i see the problem was i didn't declare i in the
class before i used it in the method definition. I
thought the way i declared it in the for loop would
work, oh well.no-no. the problem was, that you returned something only inside for loop, but compiler was not sure that thing from the for loop would be returned, so it was bitching about that...
if you had written your for statement like that:
for (int i=0; i < -1; i++) {
return i;
then body of return statement would not had been executede, therefore nothing would have got returned, and that's the case about what this compiletime error was telling you...
