Enumeration hasMoreElements() Method in Java with Examples

Last Updated : 27 Jun, 2019

An object that implements the Enumeration interface generates a series of elements, one at a time. hasMoreElements() method of Enumeration used to tests if this enumeration contains more elements. If enumeration contains more element then it will return true else false.

Syntax:

boolean hasMoreElements()

Parameters: This method accepts nothing.

Return value: This method returns true if and only if this enumeration object contains at least one more element to provide; false otherwise.

Below programs illustrate hasMoreElements() method:
Program 1:

// Java program to demonstrate 
// Enumeration.hasMoreElements() method 
  
import java.util.*; 
  
public class GFG { 
  
    @SuppressWarnings({ "unchecked", "rawtypes" }) 
    public static void main(String[] args) 
    { 
  
        Enumeration Days; 
        Vector week = new Vector(); 
  
        week.add("Sunday"); 
        week.add("Monday"); 
        week.add("Tuesday"); 
        week.add("Wednesday"); 
        week.add("Thursday"); 
        week.add("Friday"); 
        week.add("Saturday"); 
        Days = week.elements(); 
  
        while (Days.hasMoreElements()) { 
            System.out.println("Day = "
                               + Days.nextElement()); 
        } 
    } 
} 

Output:

Day = Sunday
Day = Monday
Day = Tuesday
Day = Wednesday
Day = Thursday
Day = Friday
Day = Saturday

Program 2:

// Java program to demonstrate 
// Enumeration.hasMoreElements() method 
  
import java.util.*; 
  
public class GFG { 
  
    @SuppressWarnings({ "unchecked", "rawtypes" }) 
    public static void main(String[] args) 
    { 
  
        Enumeration<Integer> classNine; 
        Vector<Integer> rollno = new Vector<Integer>(); 
  
        rollno.add(1); 
        rollno.add(2); 
        rollno.add(3); 
        rollno.add(4); 
        rollno.add(5); 
        rollno.add(6); 
        rollno.add(7); 
        rollno.add(8); 
        classNine = rollno.elements(); 
  
        while (classNine.hasMoreElements()) { 
            System.out.println("Roll No = "
                               + classNine.nextElement()); 
        } 
    } 
} 

Output:

Roll No = 1
Roll No = 2
Roll No = 3
Roll No = 4
Roll No = 5
Roll No = 6
Roll No = 7
Roll No = 8
