Program/Source Code:

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

// Java program to remove all items 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: " + countries);

    countries.clear();

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

Output:

Country names: [India, USA, UK, CANADA]
Country names: []

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 removed all items from the LinkedList collection using the clear() method and printed the result.
