question: public static String playerIdToName ( UUID uuid ) { long leastSigBits = uuid . getLeastSignificantBits ( ) ; long mostSigBits = uuid . getMostSignificantBits ( ) ; byte [ ] bytes = toArray ( mostSigBits , leastSigBits ) ; bytes = removeZeroesAtEnd ( bytes ) ; return new String ( bytes , StandardCharsets . UTF_8 ) ; }
target:  Converts an UUID back to the playername.
