In this example we shall show you how to obtain a Vector Iterator, in order to iterate through a Vector’s elements. To obtain a Vector Iterator one should perform the following steps:
- Create a new Vector.
- Populate the vector with elements, with
add(E e)API method of Vector. - Invoke
iterator()API method of Vector, to get the Iterator. - Iterate through the elements of the collection, using
hasNext()andnext()methods of Iterator,
as described in the code snippet below.

Output:
Vector elements :
element_1
element_2
element_3
element_4
element_5
This was an example of how to obtain a Vector Iterator in Java.
