Submitted by Nidhi, on April 12, 2022

Problem Solution:

In this program, we will create a LinkedList for country names using a Linked List collection. Then we will remove an item from the LinkedList collection using the remove() method and print the updated collection.

Program/Source Code:

The source code to remove an item from the LinkedList collection is given below. The given program is compiled and executed successfully.

// Java program to remove an item from 
// 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 before removing item: " + countries);

    countries.remove("USA");

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

Output:

Country names before removing item: [India, USA, UK, CANADA]
Country names after removing item: [India, 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 to the linked list using add() method. Then we removed an item from LinkedList using the remove() method and printed the updated LinkedList collection.
