Doubly Linked List Node Problems

Question

int listSize = 0;
CalendarLinkedList firstList = new CalendarLinkedList();
CalendarLinkedList currentList = firstList;
for(int a = 0; a < listSize; listSize ++)
        {
            currentList = firstList.next;
        }
        CalendarLinkedList newList = new CalendarLinkedList(todayDate, listSize + 1);
        newList.setPrev(currentList);

        currentList.setNext(newList);

        currentList = newList;

This is one part of my linked list, will the nodes be alligned properly? Because it seems like newList is not going next to currentList properly.

listSize is like a counter.

I thought if I write my codes like this, a new list will come next to firstList, then the current will become the new List. Am I wrong?

Answer 1

Assuming that the variable firstList points to the head of the list you want to add to, you probably want something like this:

int listSize = 0;
CalendarLinkedList currentList = firstList;
while (currentList.next != null)
{
    currentList = currentList.next;
    listSize++;
}
CalendarLinkedList newList = new CalendarLinkedList(todayDate, listSize + 1);
newList.setPrev(currentList);
currentList.setNext(newList);
