Circular List

Good afternoon,

I'm working on a program in which I am trying to implement a circular list. Till now I have a MainProgram where I invoke method from the Method class in which I prompt the user to enter details and return this as an object. Then I have created my circular list with methods append and show. I'm appending the object to my circular list and then i will invoke method ListAll() to show all the members of the list.

The problems I have is that i am not sure if the circular list is beign populated... and none members are beiggn shown. I know I surely have some mistakes in CircularList class but i'm stuck and cannot identify my mistakes.

Below follows my code. Thanks

import java.util.*;

Take out a pencil and paper, and walk through what your append method is doing. You will see that it doesn't do it correctly.

Go back to pen and paper (and walk through the methiod) again. You will see why.
