Solved Print all homes

Maybe some of you can help me?
I want to list all the homes a player has, but I don't know how to do...

Here is the code: https://hastebin.com/abekisajow.java

Code (open) Code (close)

Code:

package de.unbanane.commands;

import java.io.File;
import java.io.IOException;
import org.bukkit.Bukkit;
import org.bukkit.Location;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.configuration.InvalidConfigurationException;
import org.bukkit.configuration.file.YamlConfiguration;
import org.bukkit.entity.Player;

import de.unbanane.main.Main;

public class HomeCMD implements CommandExecutor {

    File homes = new File("plugins//Basics//homes.yml");
    YamlConfiguration cfg = YamlConfiguration.loadConfiguration(homes);

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String arg2, String[] args) {
        Player p = (Player) sender;

        if (p.hasPermission("basics.home")) {
            if (args.length == 1) {
                try {
                    cfg.load(homes);
                } catch (IOException | InvalidConfigurationException e) {
                    e.printStackTrace();
                }
                if (cfg.isSet(p.getName() + "." + args[0] + ".world")) {
                    try {
                        cfg.load(homes);
                    } catch (IOException | InvalidConfigurationException e) {
                        e.printStackTrace();
                    }
                    String world = cfg.getString(p.getName() + "." + args[0] + ".world");
                    double x = cfg.getDouble(p.getName() + "." + args[0] + ".X");
                    double y = cfg.getDouble(p.getName() + "." + args[0] + ".Y");
                    double z = cfg.getDouble(p.getName() + "." + args[0] + ".Z");
                    double yaw = cfg.getDouble(p.getName() + "." + args[0] + ".Yaw");
                    double pitch = cfg.getDouble(p.getName() + "." + args[0] + ".Pitch");

                    Location loc = new Location(Bukkit.getWorld(world), x, y, z);
                    loc.setPitch((float) pitch);
                    loc.setYaw((float) yaw);
                    p.teleport(loc);
                    p.sendMessage(Main.prefix + "§6You were teleported to your home: §c" + args[0] + "§6!");
                } else {
                    p.sendMessage(Main.prefix + "§cThe home " + args[0] + " doesn't exist!");
                }
            } else {
                p.sendMessage(Main.prefix + "§cPlease use: /home <name>");
            }
        } else {
            sender.sendMessage(Main.noperm);
        }
        if(args[0].equalsIgnoreCase("list")){
            //     ?
        }
        return false;
    }

}

I hope you can help me so that i can print out all homes from a player

1. Use File.seperateor instead of slashes. Hard coding the slashes like that may cause problems on different OSs.
2. Don't blidnly cast sender to a Player. Since plugins, consoles, and command blocks can all send commands, you can't just assume the sender will always be a Player. Add an instanceof check before you cast.
3. Main problem: Since the path to each home is <Player>.<HOME>, use Config#getConfigurationSection(<PLAYER>).getKeys(false) to return all the homes.
4. Remember: Always check the args length before getting args.
