Circularly Linked List

Step 3: Count elements Circularly Linked List

To count all elements of the circularly linked list, we will need a loop to traverse through the circularly linked list. We will let a link (i) of ListElem type to point to the pfirst then move the link to its next element and increase the number of item(t) one at a time by using a while loop until the end of the circularly linked list is reached.


// count the number of items in the list

public int countitem()

                ListNode<T> i;
                int t = 0;
                if (pfirst != null)
                    t = 1;

                    for (i =; i != pfirst; i =
                        t = t + 1;


                return t;
