Topological Sorting Java

Question

I have this assignment where I need to implement a topological sorting algorithm
but I can't seem to make it work.
I am not using linked lists as it is outside the scope of the course I'm taking.
the algorithm I'm supposed to use is found in the code itself (as a comment)

Answer 1

It would help the debugging process if you provided input that shows the wrong operation. I was looking at it but do not have the time to do a thorough investigation of the code itself.

Answer 2

Ani Jona 🕊 I am sorry for the late reply but my problem have been solved
I just had a logical error
Realised my mistake when I was giving more details on the code on another website
yet again, I am sorry for wasting your time ^^;
but thank you for considering to answer!

Answer 3
