//Printing the elements using iterator
Iterator itr=list.iterator();
while(itr.hasNext())
System.out.println(itr.next());

//Adding elements First and Last
list.addFirst(1);
System.out.println(list);

list.addLast(99);
System.out.println(list);

System.out.println("Get the size of List"+list.size());

//Sort the list using Collections Sort
Collections.sort(list);
System.out.println(list);

//Get the sublist from list
System.out.println(list.subList(2, 4));

//Stack Operations Using Linked List
System.out.println(list.peek());
System.out.println(list.poll());
System.out.println(list.pop());
