    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...

        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) {
                    firstIteration = false;
                else {
            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 {
                        } 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?
