Problem Solution:

In this program, we will create a LinkedList for country names using a Linked List collection. Then we will add an item to LinkedList at the specified index using add() method.

Program/Source Code:

The source code to add an item into the LinkedList collection on the specified index is given below. The given program is compiled and executed successfully.

// Java program to add an item into LinkedList collection 
// on the specified index

import java.util.LinkedList;

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


    System.out.println("Country names: " + countries);

    countries.add(1, "CHINA");

    System.out.println("Country names: " + countries);


Country names: [India, USA, UK, CANADA]
Country names: [India, CHINA, USA, UK, CANADA]


In the above program, we imported the "java.util.LinkedList" package 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 the object of the LinkedList collection class to store country names. Here, we added the items to the linked list using add() method. Then we added "CHINA" into the countries collection at index 1 using add() method and printed the updated collection.
