Java Collections emptyListIterator() Method with Examples

// Java program to run the iterator with no elements
import java.util.*;

public class GFG {
  
    // main method
    public static void main(String[] args)
    {
        // create an list iterator
        ListIterator<String> iterator
            = Collections.emptyListIterator();
      
        // get the elements which is empty
        System.out.println(iterator.hasNext());
    }
}

// Java program to iterate the elements with a list
// of elements. Here we will get an error 
// because the list is not empty
import java.util.*;

public class GFG {
    // main method
    public static void main(String[] args)
    {
        // create an array list
        List<Integer> data = new ArrayList<Integer>();
           
        // add 2 elements into the array list
        data.add(100);
        data.add(200);      
      
        // iterate the elements
        ListIterator<String> iterator
            = Collections.emptyListIterator(); 
      
          // display            
        System.out.println(iterator.next());
    }
}

// Java program to display next index
// and previous index element
import java.util.*;
public class GFG {

    // main method
    public static void main(String[] args)
    {

        // create an array list

        // add 2 elements into the array list
        data.add(100);
        data.add(200);

        // iterate the elements
        ListIterator<String> iterator
            = Collections.emptyListIterator();
        System.out.println(iterator.nextIndex());

        // display previous element
