Looping a UUID in a YML file

How would I loop through unique UUID's in my config? For example, if I have this:

Code:

9eaf2e85-9784-48b9-bdb5-4593de0db4d0:
  uuid: 9eaf2e85-9784-48b9-bdb5-4593de0db4d0
  race: Elf
  exp: 6373
  level: 48
1d30686f-649c-4c8c-90e2-fb14cd140d59:
  uuid: 1d30686f-649c-4c8c-90e2-fb14cd140d59
  race: Orc
  exp: 1834
  level: 13

There will always be new UUID's coming through as player's join the server. If I have this command in my `Commands.java` class:

Code:

if (lable.equalsIgnoreCase("update")) {
  File file = new File(Bukkit.getPluginManager().getPlugin("DummyPlugin").getDataFolder(), "config.yml");
  FileConfiguration otherFile = YamlConfiguration.loadConfiguration(file);
          
  String fileConfig = otherFile.getString("test");
  Bukkit.getLogger().info(fileConfig);
  core.otherLog("[" + format.format(now) + "]" + "Successfully got info from the plugin 'DummyPlugin'. Message: " + fileConfig);
  core.otherLog("e");
}

I'll need to loop through each UUID, take that information, that insert it into a database. But what stumps me is how to loop through them... How would I accomplish this?

Commands.java:

Code:

package eltik.connection.sql;
import java.io.File;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.UUID;
import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.configuration.file.YamlConfiguration;
import org.bukkit.entity.Player;
public class Commands implements CommandExecutor {
  
    Core core = Core.getPlugin(Core.class);
  
    public Commands(Core core) {
        this.core = core;
        Bukkit.getPluginCommand("update").setExecutor(this);
    }
  
    Date now = new Date();
    SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
  
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String lable, String[] args) {
        Player player = (Player) sender;
        String playerName = player.getName();
        UUID uuid = player.getUniqueId();
        if (lable.equalsIgnoreCase("update")) {
            File file = new File(Bukkit.getPluginManager().getPlugin("DummyPlugin").getDataFolder(), "config.yml");
            FileConfiguration otherFile = YamlConfiguration.loadConfiguration(file);
          
            String fileConfig = otherFile.getString("test");
            Bukkit.getLogger().info(fileConfig);
            core.otherLog("[" + format.format(now) + "]" + "Successfully got info from the plugin 'DummyPlugin'. Message: " + fileConfig);
            core.otherLog("e");
        }
        return false;
    }
}

 

Get a ConfigurationSection object then loop the keys from it.

Code:

ConfigurationSection cfg = (plugin object).getConfig().getConfigurationSection("");
if (cfg == null) {
  sender.sendMessage("No UUIDs have been logged.");
  return;
}

for (String uuidText : cfg.getKeys(false)) {
  sender.sendMessage(uuidText + "'s race is " + cfg.getString(uuidText + ".race", "Unknown"));
}

It seems redundant by the way to key on UUID then have UUID as a subkey.

PS you also should check if sender is a Player before casting it thus.
