Vector Iterator example
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.
package com.javacodegeeks.snippets.core; import java.util.Vector; import java.util.Iterator; public class VectorIteratorExample { public static void main(String[] args) { // Create a Vector and populate it with elements Vector vector = new Vector(); vector.add("element_1"); vector.add("element_2"); vector.add("element_3"); vector.add("element_4"); vector.add("element_5"); // The Iterator object is obtained using iterator() method Iterator it = vector.iterator(); // To iterate through the elements of the collection we can use hasNext() and next() methods of Iterator System.out.println("Vector elements :"); while(it.hasNext()) System.out.println(it.next()); } }
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.
