   public static void main(String[] args) {
      LinkedList lList = new LinkedList();
      lList.add("1");
      lList.add("2");
      lList.add("3");
      lList.add("4");
      lList.add("5");
      System.out.println(lList);
      lList.addFirst("0");
      System.out.println(lList);
      lList.addLast("6");
