[anita dhar]

import java.util.*;
class Flubber
{
public static void main(String[] args)
List<String> x = new ArrayList<String>();
x.add("x");
x.add("xx");
x.add("Xx");

// insert code here
for(String s: x)
System.out.println(s);

And output :
xx
Xx
x



which code inserted at // insert code here . will produce the preeceding output ?
(choose all that apply)

A . Collection.sort(x);

B . Comparable c = Collection.reverse();
Collections.sort(x,c);
C . Comparator c = Collection.reverse();
Collections.sort(x,c);
D . Comparable c = Collection.reverseOrder();
Collections.sort(x,c);
E. Comparator c = Collection.reverseOrder();
Collections.sort(x,c);
