Examples of java.util.ListIterator

java.util.ListIterator
An iterator for lists that allows the programmer to traverse the list in either direction, modify the list during iteration, and obtain the iterator's current position in the list. A ListIterator has no current element; its cursor position always lies between the element that would be returned by a call to previous() and the element that would be returned by a call to next(). An iterator for a list of length n has n+1 possible cursor positions, as illustrated by the carets (^) below:
```
 Element(0)   Element(1)   Element(2)   ... Element(n-1) cursor positions:  ^            ^            ^            ^                  ^ 
```
Note that the {@link #remove} and {@link #set(Object)} methods arenot defined in terms of the cursor position; they are defined to operate on the last element returned by a call to {@link #next} or {@link #previous()}.
