Given a pre-generics implementation of a method:
11. public static int sum(List list) {
12. int sum = 0;
13. for ( Iterator iter = list.iterator(); iter.hasNext(); ) {
14. int i = ((Integer)iter.next()).intValue();
15. sum += i;
16. }
17. return sum;
18. }
What three changes allow the class to be used with generics and avoid an unchecked warning?
(Choose three.)
A.
Remove line 14.
B.
Replace line 14 with “int i = iter.next();”.
C.
Replace line 13 with “for (int i : intList) {“.
D.
Replace line 13 with “for (Iterator iter : intList) {“.
E.
Replace the method declaration with “sum(List<int> intList)”.
F.
Replace the method declaration with “sum(List<Integer> intList)”.
