    Exception in thread "main" java.lang.UnsupportedOperationException: Not supported yet.
    at quantockcoaches.BillingAndTicketing.<init>(Billing AndTicketing.java:27)
    That exception is explicitly thrown by the code at line 27 in BillingAndTicketing.
    If you don't want that exception to be thrown then
    either do not call that constructor
    or remove the throw statement and replace it with some useful code.
    If you don't understand my answer, don't ignore it, ask a question.

    Thank you very much for your response, I swapped the code snippet from the first constructor into the one with the throw statement and it worked perfectly with a bit of tweeking for appearances
