import java.util.HashSet;

import java.util.Set;

/*
 * Example of addAll(Collection<? extends E> c) method
 */
public class LinkedListAddAllIndexBasedExample
{

    public static void main( String[] args )
    {
        LinkedList<Integer> linkedList = new LinkedList<Integer>();
        linkedList.add(1);
        linkedList.add(2);
        linkedList.add(3);

        System.out.println("linkedList : " + linkedList);

        Set<Integer> set = new HashSet<Integer>();
        set.add(4);
        set.add(5);

        System.out.println("set : " + set);
        
        /*
         * In Position 1 adding Set collection elements to the list collection
         */

        linkedList.addAll(1,set);

        System.out.println("linkedList : " + linkedList);
    }

}

Output
linkedList : [1, 2, 3]
set : [4, 5]
linkedList : [1, 4, 5, 2, 3]
