In this method, you can check for further elements in a collection, one element at a time in forward direction when traversing in a collection.
hasNext( ) method of ListIterator Interface in java.
In the following example we will show you how can hasNext( ) method be implemented in ListIterator interface.
Syntax
boolean hasNext( )
This method returns 'true' while traversing the list in forward direction, and a collection keeps more elements otherwise. returns 'false'.
In this method, you can check for further elements in a collection, one element at a time in forward direction when traversing in a collection. This method is used with ListIterator object. It is useful for checking the availability of more elements in the next position in a collection.
Parameter description
This method does not take any argument.
Example of hasNext( ) method
In this example we will show you how does hasNext( ) method work in a collection in forward direction. This example will help you to understand how can you check for existence of more elements in collection. Through this example we will show you how listIterator( ) method is used and how the hasNext( ) method is used for checking the availability of more elements with ListIterator object in a collection.
Example:-
package Devmanuals.com;
import java.util.List;
import java.util.LinkedList;
import java.util.ListIterator;
public class ListIteratorHasNext {
public static void main(String[] args) {
LinkedList llist = new LinkedList();
llist.add("Bipul");
llist.add("Kumar");
llist.add("Choudhary");
llist.add("Age");
llist.add("23");
ListIterator litr = llist.listIterator();
boolean b = litr.hasNext();
System.out.println("List has elements : " + b);
System.out.println("Elements of list = " + llist);
System.out.println("Size of list = " + llist.size());
}
}
Output :
|
List has elements : true Elements of list = [Bipul, Kumar, Choudhary, Age, 23] Size of list = 5 |
