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.
