i am trying to use the ready type of linked list and i found that there is
a bug in the add.(index, object) method.
i am trying to read the index after each addition is performed and the
value i get is always 0.
when i am trying to extract data from the list thow the index is working
as expected and i can move about doing all the described operations
I am attaching a sample programm to demonstrate the problem
tks for the help
