Not sure where to post this, and not much happening here, but hopefully this basic junk is useful to somebody as I find it works quite well for me when storing and retrieving values from a database... It's just a couple methods that pile a bunch of UUIDs together in one string from an ArrayList, and alternatively create a bunch of UUID objects in an ArrayList from a string... Hopefully it's useful to somebody, it works great for me, fairly basic... Code: private static final char UUID_SEPARATOR = ','; protected String uuidListToString(ArrayList<UUID> uuids) { StringBuilder uuidList = new StringBuilder(); boolean firstIteration = true; for (UUID currentUuid : uuids) { if (firstIteration) { uuidList.append(currentUuid.toString()); firstIteration = false; } else { uuidList.append(UUID_SEPARATOR).append(currentUuid.toString()); } } return uuidList.toString(); } public static ArrayList<UUID> uuidListFromString(String string) { ArrayList<UUID> uuids = new ArrayList<>(); if (string != null) { char[] stringArray = string.toCharArray(); String currentUuidString = ""; for (int i = 0; i < string.length(); i++) { if (stringArray[i] != UUID_SEPARATOR) { currentUuidString += stringArray[i]; } else { try { uuids.add(UUID.fromString(currentUuidString)); } catch (IllegalArgumentException e) { YOUR_PLUGIN.getPlugin().getLogger().warning("Could not parse UUID from string"); } currentUuidString = ""; } } } return uuids; }
Moved to resources @w0lv3s And why would you put them together in the same string? Why not just save them as a list?
