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
