LinkedList <String> l_list = new LinkedList <String> ();
// use add() method to add values in the linked list
l_list.add("Red");
l_list.add("Green");
l_list.add("Black");
l_list.add("Pink");
l_list.add("orange");
// print the list
System.out.println("Linked list before shuffling:\n" + l_list);
Collections.shuffle(l_list);
System.out.println("Linked list after shuffling:\n" + l_list);
