Stack listIterator() method in Java with Example

The listIterator() method of Java.util.Stack class is used to return a list iterator over the elements in this stack (in proper sequence). The returned list iterator is fail-fast.

Syntax:

public ListIterator listIterator()

Return Value: This method returns a list iterator over the elements in this stack (in proper sequence).

Below are the examples to illustrate the listIterator() method.

Example 1:




// Java program to demonstrate
// listIterator() method
// for String value
  
import java.util.*;
  
public class GFG1 {
    public static void main(String[] argv) throws Exception
    {
        try {
  
            // Creating object of Stack<Integer>
            Stack<String>
                stack = new Stack<String>();
  
            // adding element to stack
            stack.add("A");
            stack.add("B");
            stack.add("C");
            stack.add("D");
  
            // print stack
            System.out.println("Stack: "
                               + stack);
  
            // Creating object of ListIterator<String>
            // using listIterator() method
            ListIterator<String>
                iterator = stack.listIterator();
  
            // Printing the iterated value
            System.out.println("\nUsing ListIterator:\n");
            while (iterator.hasNext()) {
                System.out.println("Value is : "
                                   + iterator.next());
            }
        }
  
        catch (NullPointerException e) {
            System.out.println("Exception thrown : " + e);
        }
    }
}


Output:

Stack: [A, B, C, D]

Using ListIterator:

Value is : A
Value is : B
Value is : C
Value is : D

Program 2:




// Java code to illustrate lastIndexOf()
import java.util.*;
  
public class StackDemo {
    public static void main(String args[])
    {
  
        // Creating an empty Stack
        Stack<Integer> stack = new Stack<Integer>();
  
        // Use add() method to add elements in the Stack
        stack.add(1);
        stack.add(2);
        stack.add(3);
        stack.add(10);
        stack.add(20);
  
        // Displaying the Stack
        System.out.println("Stack: " + stack);
  
        // Creating object of ListIterator<String>
        // using listIterator() method
        ListIterator<Integer>
            iterator = stack.listIterator();
  
        // Printing the iterated value
        System.out.println("\nUsing ListIterator:\n");
        while (iterator.hasNext()) {
            System.out.println("Value is : "
                               + iterator.next());
        }
    }
}


Output:

Stack: [1, 2, 3, 10, 20]

Using ListIterator:

Value is : 1
Value is : 2
Value is : 3
Value is : 10
Value is : 20
