interators problems

Trace the method addToList() that inserts a new item into a list.

public static <T> void addToList(LinkedList<T> list, T item)

{

Iterator<T> iter = list.iterator();

while (iter.hasNext())

if (item.equals(iter.next()))

return;

list.add(item);

}

A) Consider the empty LinkedList intList and the Integer array arr.

LinkedList<Integer> intList = new LinkedList<Integer>();

Integer[] arr = {5, 2, 4, 5, 7, 2};

What are the elements in intList after executing the loop?

for(int i=0; i<arr.length; i++)

addToList(intList, arr);

B) Assume LinkedList charList is an empty collection of Character type and string str = "mississippi". What are the elements in charList after executing the loop?

for (int i =0; i><str.length(); i++)

addToList(charList, str.charAt(i));>
