Question

I’d like to know if I can get the first element of a list or set. Which method to use?

Answer 1

Collection c;

Iterator iter = c.iterator();

Object first = iter.next();

(This is the closest you’ll get to having the “first” element of a Set. You should realize that it has absolutely no meaning for most implementations of Set. This may have meaning for LinkedHashSet and TreeSet, but not for HashSet.)
