Iterate through elements Java Vector using ListIterator Example
This Java Example shows how to iterate through the elements of java
Vector object in forward and backward direction using ListIterator.

Get a ListIterator object for Vector using
listIterator() method.

Use hasNext() and next() methods of ListIterator to iterate through
the elements in forward direction.
*/

Use hasPrevious() and previous() methods of ListIterator to iterate through
the elements in backward direction.

Output would be
Iterating through Vector elements in forward direction...
