Enumeration hasMoreElements() Method in Java with Examples

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

// 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

// 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
