Problem statement

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

Source Code

The source code to insert an element at the end of the LinkedList collection is given below. The given program is compiled and executed successfully.

// Java program to insert an element at the end of 
// the LinkedList collection

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: " + countries);

    countries.addLast("JAPAN");

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

Output

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

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 added "JAPAN" at the end of LinkedList using the addLast() method. After that, we printed the updated LinkedList.
