The Java.util.Vector.iterator() method is used to return an iterator of the same elements as that of the Vector. The elements are returned in random order from what was present in the vector.
Syntax:
Iterator iterate_value = Vector.iterator();
Parameters: The function does not take any parameter.
Return Value: The method iterates over the elements of the vector and returns the values(iterators).
Below program illustrates the use of Java.util.Vector.iterator() method:
Example 1:
// Java code to illustrate iterator() import java.util.*; import java.util.Vector; public class VectorDemo { public static void main(String args[]) { // Creating an empty Vector Vector<String> vector = new Vector<String>(); // Use add() method to add elements into the Vector vector.add( "Welcome" ); vector.add( "To" ); vector.add( "Geeks" ); vector.add( "4" ); vector.add( "Geeks" ); // Displaying the Vector System.out.println( "Vector: " + vector); // Creating an iterator Iterator value = vector.iterator(); // Displaying the values // after iterating through the vector System.out.println( "The iterator values are: " ); while (value.hasNext()) { System.out.println(value.next()); } } } |
Vector: [Welcome, To, Geeks, 4, Geeks] The iterator values are: Welcome To Geeks 4 Geeks
Example 2:
// Java code to illustrate hashCode() import java.util.*; public class VectorDemo { public static void main(String args[]) { // Creating an empty Vector Vector<Integer> vector = new Vector<Integer>(); // Use add() method // to add elements into the Vector vector.add( 10 ); vector.add( 20 ); vector.add( 30 ); vector.add( 40 ); vector.add( 50 ); // Displaying the Vector System.out.println( "Vector: " + vector); // Creating an iterator Iterator value = vector.iterator(); // Displaying the values // after iterating through the vector System.out.println( "The iterator values are: " ); while (value.hasNext()) { System.out.println(value.next()); } } } |
Vector: [10, 20, 30, 40, 50] The iterator values are: 10 20 30 40 50
