Submitted by Nidhi, on April 13, 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 first item from LinkedList without removing it using the element() method.

Program/Source Code:

The source code to get the first element from the LinkedList without removing it is given below. The given program is compiled and executed successfully.

// Java program to get the first element from the 
// LinkedList without removing it

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("First element: " + countries.element());

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

Output:

First element: India
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 first element of the LinkedList without removing it using the element() method and printed the result.
