An object that implements the Enumeration interface generates a series of elements, one at a time. The nextElement() method of Enumeration used to return the next element of this enumeration if this enumeration object has at least one more element to provide.This method is used to get elements from the enumeration. Syntax:
E nextElement()
Parameters: This method accepts nothing. Return value: This method returns true the next element of this enumeration. Exception: This method throws NoSuchElementException if no more elements exist. Below programs illustrate nextElement() method: Program 1:
Java
// Java program to demonstrate// Enumeration.nextElement() methodimport java.util.*;public class GFG { @SuppressWarnings({ "unchecked", "rawtypes" }) public static void main(String[] args) { // create a Enumeration and vector object Enumeration<Integer> company; Vector<Integer> employees = new Vector<Integer>(); // add values to employees employees.add(1001); employees.add(2001); employees.add(3001); employees.add(4001); company = employees.elements(); while (company.hasMoreElements()) { // get elements using nextElement() System.out.println("Emp ID = " + company.nextElement()); } }} |
Output:
Emp ID = 1001 Emp ID = 2001 Emp ID = 3001 Emp ID = 4001
Program 2:
Java
// Java program to demonstrate// Enumeration.nextElement() methodimport java.util.*;public class GFG { @SuppressWarnings({ "unchecked", "rawtypes" }) public static void main(String[] args) { // create a Enumeration and vector object Enumeration<String> Users; Vector<String> user = new Vector<String>(); // add Users user.add("Aman Singh"); user.add("Raunak Singh"); user.add("Siddhant Gupta"); Users = user.elements(); while (Users.hasMoreElements()) { // get elements using nextElement() System.out.println(Users.nextElement()); } }} |
Output:
Aman Singh Raunak Singh Siddhant Gupta
