Java nextElement()

In this section, you will get the detailed explanation about the nextElement() method of interface Enumeration. We are going to use nextElement() method of interface Enumeration in Java. The description of the code is given below for the usage of the method.

Description of the code:

Here, you will get to know about the nextElement() method through the following java program. This method returns next element of the enumeration in case the enumeration has more than one element. This means that if the enumeration has more than one element then the nextElement() method will return the next element. However, if no more element exist then it throws NoSuchElementException.

In the program code given below, we have taken a Vector of string type. Then we have applied the hasMoreElement() method which will check for the next element and if it will find the next element then it will return that with the help of nextElement() method.

Here is the code of program:


import java.util.Enumeration; 

import java.util.Vector; 

import java.util.*;



 public class nextElement{  

 public static void main (String[] args){ 

 

 Vector strVector = new Vector(); 

 String str = new String();

 strVector.addElement(new String("Hi")); 

 strVector.addElement(new String("Hello")); 

 strVector.addElement(new String("Namaste")); 

 strVector.addElement(new String("Salam")); 

 

 Enumeration elements = strVector.elements(); 

 while (elements.hasMoreElements()){  

 str = (String)elements.nextElement(); 

 System.out.println(str); 

 }  

 }  

 }

Output of the program:

C:\unique>javac nextElement.java

C:\unique>java nextElement
Hi
Hello
Namaste
Salam

C:\unique>
