Minecraft UUID fetcher

FetchUUID.java

import org.bukkit.Bukkit;
import org.bukkit.OfflinePlayer;

import java.util.Optional;
import java.util.UUID;

public class FetchUUID {


    public FetchUUID() {
    }

    public static Optional<UUID> getID(String user) {
        OfflinePlayer p = Bukkit.getOfflinePlayer(user);
            return Optional.of(p.getUniqueId());
    }

}

A safe UUID fetcher - it will never return null but it might be empty. My typical use is:

        if (!Bukkit.getPlayer(String.valueOf(FetchUUID.getID(buyer))).hasPlayedBefore()) {
            if (!seller.hasPlayedBefore()) {
                sender.sendMessage("Player not found on this server");
                return;

            }
        }
