// use add() method to add values in the linked list
l_list.add("Red");
l_list.add("Green");
l_list.add("Black");
// print original list
System.out.println("Original linked list:" + l_list);
// create a new collection and add some elements
LinkedList <String> new_l_list = new LinkedList <String> ();
new_l_list.add("White");
new_l_list.add("Pink");
// Add the collection in the second position of the existing linked list
l_list.addAll(1, new_l_list);
