Submitted by Nidhi, on April 14, 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 get the items from the LinkedList using the get() method based on the index and print them.

Program/Source Code:

The source code to get the items from the LinkedList collection using the index is given below. The given program is compiled and executed successfully.

// Java program to get the items from LinkedList collection
// using the index

import java.util.LinkedList;

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");

    System.out.println("Country names: ");
    for (int i = 0; i < 4; i++) {
      System.out.println(countries.get(i));
    }
  }
}

Output:

Country names: 
India
USA
UK
CANADA

Explanation:

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 an object of the LinkedList collection class to store country names. Here, we added country names using add() method. Then we get the elements from LinkedList based on the index using the get() method and printed them.
