Implicit requirement on class and variable names in lab04

[tygq13]

Summary

Lab04 require "BookingStub" class but this is not mentioned in task.txt.

Description:

I fail at this question where it has implicit requirement on this class "BookingStub" and variable "list", but this requirement is not mentioned in the task.txt. I have my own implementation that can pass the sample test cases but failed at codecrunch. My worries is that in the PE where we only have one time to submit the code, how can we know the class names and variable names required by the grader which is not explicitly mentioned in task.txt?

Isn't this due to runtime error? I am facing the same issue and it shows runtime error at the top.

I'm not sure why it's happening, but I think it's trying to go through a bunch of test cases in a list and for some reason the list can't be loaded. I didn't have to implement class BookingStub so I don't think it's required.

I didn't implement the class BookingStub and variable list. I think those are part of the private sample cases within code crunch that tests for edge cases. It's possible that they failed to run as a result of runtime error.

I'm facing a similar issue for test case 3. Not sure why a sort method for class BookingStub has to be implemented?

Gave my TA a ping to notify on this issue. Was also affected by these testcases after 2/5. Likely that the past iterations of this Lab was done using class BookingStub instead of Booking?

Currently facing the same issue too, wondering why there has to be a sort method.

hi! I might be entirely wrong, but I think that BookingStub may be extending on your Booking.java class and is attempting to sort certain bookings to check your code. Not sure if this is why the error occurs, but maybe you can check on whether you have implemented Comparable and coded the compareTo method correctly?

Is the class/interface that NormalCab is a child of named Driver? If not you can try renaming it.

This worked for me, seems like we have to use specific Class names in the PE exam as well (I named it CabDriver instead of Driver originally)

This works for me as well. Probably from past iterations, the cabs must inherit/implement the Driver class/interface and then there is probably some modification from the past that makes us don't know that we have to use that specific naming.

Also another one is to rename your jsh from level 5 to level5.jsh.

As for this, I think it's not always the case, feels like a clarity issue to me 😕

The test case worked without submitting the Comparator interface. It is conflicting with Codecrunch's own. Hope it works for you

Thank you so much! It worked after I dropped my Comparable interface from the submission files. I misunderstood the text to mean that I had to create my own Comparable interface.
