Java program to iterate linked list elements from the specified position

Java example to iterate linked list elements from the specified position.
Submitted by Nidhi, on April 21, 2022

Problem Solution:

In this program, we will create a Linked List for country names using a Linked List collection. Then we will add items using add() method. After that, we will use ListIterator to iterate list items from the specified position.

Program/Source Code:

The source code to iterate linked list elements from the specified position is given below. The given program is compiled and executed successfully.

// Java program to iterate linked list elements 
// from specified position

import java.util.LinkedList;
import java.util.ListIterator;

public class Main {
  public static void main(String[] args) {
    LinkedList < String > countries = new LinkedList < String > ();

    countries.add("India");
    countries.add("USA");
    countries.add("UK");
    countries.add("CANADA");
    countries.add("USA");
    countries.add("PAK");

    ListIterator itr = countries.listIterator(2);

    System.out.println("Countries are:");
    while (itr.hasNext()) {
      System.out.print(itr.next() + " ");
    }
  }
}

Output:

Countries are:
UK CANADA USA PAK 

Explanation:

In the above program, we imported the "java.util.LinkedList" and java.util.ListIterator packages to use the LinkedList collection class. Here, we created a class Main. The Main class contains a main() method. The main() method is the entry point for the program.

In the main() method, we created an object of the LinkedList collection class to store country names. And, added country names using add() method. Then we iterated the list items using ListIterator class and its method from index 2 and printed the result.
