There's a lot that could be said about this code, but the worst is that it has an incorrectly implemented swap when one exists in the standard collections library. I don't understand why you would show off a feature (which admittedly has an some poor interactions with other aspects of the language) while simultaneously neglecting the standard library and all the language improvements that happened between 1 and 8. Java doesn't need anymore disservices.
