Below program illustrate the Java.util.LinkedList.clone() method:

// Java code to illustrate clone() method
import java.io.*;
import java.util.LinkedList;

public class LinkedListDemo {

    public static void main(String args[]) {

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

        // Use add() method to add elements in the list
        list.add("Geeks");
        list.add("for");
        list.add("Geeks");
        list.add("10");
        list.add("20");

        // Displaying the list
        System.out.println("First LinkedList:" + list);

        // Creating another linked list and copying
        LinkedList sec_list = new LinkedList();
        sec_list = (LinkedList) list.clone();

        // Displaying the other linked list
        System.out.println("Second LinkedList is:" + sec_list);
    }
}
