import java.util.LinkedList;

public class GFG {
    public static void main(String args[]) {

        // Creating an empty LinkedList
        LinkedList<String> l = new LinkedList<>();

        // Using add() method to add 
        // elements in the LinkedList
        l.add("Geeks");
        l.add("for");
        l.add("Geeks");

        System.out.println("Original LinkedList: " + l);

        // Clearing the LinkedList
        l.clear();

        // Accessing the LinkedList 
        // after clearing it
        System.out.println(
            "List after clearing all elements: " + l);

    }
