Write some code that will use an iterator to interchange the items in every pair of items in an instance of StringLinkedListWithIterator in Listing 12.9. For example, if the list contains "a", "b", "c", "d", "e", and "f", after the code runs, it will contain "b", "a", "d", "c", "f", and "e". You can assume that the list contains an even number of strings.

Question

What will be an ideal response?

Answer 1

```
list.resetIteration();
while(list.moreToIterate()){
String toSwitch = list.getDataAtCurrent();
list.deleteCurrentNode();
list.insertNodeAfterCurrent(toSwitch);
list.goToNext();
list.goToNext();
}
System.out.println("Every pair of strings should have their”
+ “ order swapped.");
list.showList();
```

This code is in StringLinkedIteratorFragments.java.
