iterator() method of Vector class that is present inside java.util package 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 Type: The method iterates over the elements of the vector and returns the values(iterators).
Example 1:
Java
// Java code to illustrate iterator() Method// of Vector class// Importing required classesimport java.util.*;import java.util.Vector;// Main classpublic class GFG { // Main driver method public static void main(String args[]) { // Creating an empty Vector of string type Vector<String> vector = new Vector<String>(); // Adding elements into the Vector // using add() method vector.add("Welcome"); vector.add("To"); vector.add("Geeks"); vector.add("4"); vector.add("Geeks"); // Printing and displaying the Vector System.out.println("Vector: " + vector); // Now creating an iterator Iterator value = vector.iterator(); // Display message only System.out.println("The iterator values are: "); // Condition holds true till there is single element // remaining using hasNext() method while (value.hasNext()) { // Displaying the values // after iterating through the vector System.out.println(value.next()); } }} |
Output:
Vector: [Welcome, To, Geeks, 4, Geeks] The iterator values are: Welcome To Geeks 4 Geeks
Example 2:
Java
// Java code to illustrate iterator() method usage// with usage of hashCode() method// Importing required classesimport java.util.*;// Main classpublic class GFG { // Main driver method public static void main(String args[]) { // Creating an empty Vector of integer type Vector<Integer> vector = new Vector<Integer>(); // Adding custom elements into the Vector // using add() method 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(); // Display message for better readability System.out.println("The iterator values are: "); // Holds true till there is single element while (value.hasNext()) { // Printing the values after iterating // through the vector // using next() method System.out.println(value.next()); } }} |
Output:
Vector: [10, 20, 30, 40, 50] The iterator values are: 10 20 30 40 50
