@Mhael, I'm pretty sure it's just a regular program, he never tampered with the print statements. The green text is user input (not sure what it's called in Java).
@SublimeLime, if he made it, then he states what it prints for example if I say system.out.println("scrub");
That will print "scrub" so I made it print what I asked it to.... So he printed the responses to his input... Which makes the joke a LOT less funny...
I once made a rock-paper-scissors program on matlab and put in a cheat code so that Chuck Norris would override every option and just win automatically. So basically I put it in for when I felt like I might lose to the computer...
@BiteMyShinyMetalA55, for a group project my team made an Uno game and I wrote the "AI" and my professor could not beat it, even after seeing the code (its strategy).
