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.
