Are you my programming professor perchance? Sure, if the mafia points a gun at my head and forces me write an IBAN validation algorithm in valid Java code on a piece of paper, then I’m happy to oblige. But when does that ever happen? Why use Netbeans with light theme? Why are you forcing us to demonstrate bubble sort with a Hungarian folk dance? I’m asking too many questions. You probably put too much crack in your coffee today.
