Problem Solution:

In this program, we will create a LinkedList for country names using the Linked List collection class and print them.

Program/Source Code:

The source code to throw an exception explicitly is given below. The given program is compiled and executed successfully.

// Java program to create a simple Linked-List 
// using LinkedList collection class

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(countries);
  }
}

Output:

[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 the object of the LinkedList collection class to store country names. Here we added the items into the linked list using add() method and printed the created collection.
