Vector iterator() method in Java with Examples Last Updated : 17 Dec, 2021 Summarize Suggest changes Share Like Article Like Report 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 classes import java.util.*; import java.util.Vector; // Main class public 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 classes import java.util.*; // Main class public 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 Advertise with us Next Article Java Vector elementAt() Method T theprogrammedwords Follow Similar Reads Java Vector contains() Method The contains() method in Java is used to check whether a specific element is present in the Vector or not.Example 1: In this example, we will check whether a particular string is present in the vector or not.Java// Java program to demonstrate the use // of the contains() method with Strings import j 3 min read Java Vector containsAll() Method In Java, the containsAll() method is used to check if the Vector contains all the elements of a specified Collection or not.Example 1: Below program demonstrating the use of containsAll() method with Strings.Java// Java Program to demonstrate the use of // containsAll() with Strings import java.util 2 min read Java Vector copyInto() Method In Java, the copyInto() method is used to copy all the components from one vector to another array, having enough space to hold all of the components of the vector. It is to be noted that the index of the elements remains unchanged. The elements present in the array are replaced by the elements of t 3 min read Java Vector elementAt() Method In Java, the elementAt() method is used to fetch or retrieve an element at a specific index from a Vector. It allows to access elements in the vector by providing the index, which is zero-based.Example 1: Here, we use the elementAt() method to retrieve an element at a specified index with an Integer 2 min read Java Vector elements() Method In Java, the elements() method is used to return an enumeration of the elements in the Vector. This method allows you to iterate over the elements of a Vector using an Enumeration, which provides methods for checking if there are more elements and retrieving the next element.Example 1: Below is the 2 min read Vector ensureCapacity() method in Java with Example The ensureCapacity() method of Java.util.Vector class increases the capacity of this Vector instance, if necessary, to ensure that it can hold at least the number of elements specified by the minimum capacity argument. Syntax: public void ensureCapacity(int minCapacity) Parameters: This method takes 2 min read Vector equals() Method in Java The java.util.vector.equals(Object obj) method of Vector class in Java is used verify the equality of an Object with a vector and compare them. The list returns true only if both Vector contains same elements with same order. Syntax: first_vector.equals(second_vector) Parameters: This method accepts 2 min read Vector firstElement() Method in Java The java.util.vector.firstElement() method in Java is used to retrieve or fetch the first element of the Vector. It returns the element present at the 0th index of the vector Syntax: Vector.firstElement() Parameters: The method does not take any parameter. Return Value: The method returns the first 2 min read Vector forEach() method in Java The forEach() method of Vector is used to perform a given action for every element of the Iterable of Vector until all elements have been Processed by the method or an exception occurs. The operations are performed in the order of iteration if the order is specified by the method. Exceptions thrown 3 min read Vector hashCode() Method in Java The java.util.vector.hashCode() method in Java is used to get the hashcode value of this vector. Syntax: Vector.hashCode() Parameters: The method does not take any parameter. Return Value: The method returns hash code value of this Vector which is of Integer type. Below programs illustrate the Java. 2 min read Article Tags : Java Practice Tags : Java Like
