• public void addFirst(E e)及addLast(E e)
• public E getFirst()及getLast()
• public E removeFirst()及public E removeLast()
• public E get(int index);

LinkedList list = new LinkedList();
list.addFirst("a");
list.addFirst("b");
list.addFirst("c");
list.addFirst("d");
list.addLast("e");

//System.out.println(list.getFirst());
//System.out.println(list.getLast());
//System.out.println(list.removeFirst());
//System.out.println(list.removeLast());

System.out.println(list.get(1));
