Getting INT from config.yml

Good evening, i am new at programming, and i need some help.
I want to get X position from config, and its not working. Can you help me please ?

Code:

package me.MobArena.main;

import org.bukkit.Location;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin implements Listener {
   
    public void onEnable() {
        getLogger().info("Plugin Enabled");
        saveConfig();
    }
   
    public void onDisable() {
        getLogger().info("Plugin Disabled");
        saveConfig();
    }
   
    // SETSPAWN
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] arg) {
        if(sender instanceof Player) {
            if(cmd.getName().equalsIgnoreCase("setspawn1")) {
                Player p = (Player) sender;
                Location l1 = p.getLocation();
                int x1, y1, z1;
                x1 = l1.getBlockX();
                y1 = l1.getBlockY();
                z1 = l1.getBlockZ();
               
                getConfig().set(x1 + " " + y1 + " " + z1, "Spawn1 ");
                saveConfig();
               
                p.sendMessage("Suradnice su : " + l1.getBlockX() + " " + l1.getBlockY() + " " + l1.getBlockZ());
            }
           
            if(cmd.getName().equalsIgnoreCase("setspawn2")) {
                Player p = (Player) sender;
                Location l2 = p.getLocation();
               
                int x2, y2, z2;
                x2 = l2.getBlockX();
                y2 = l2.getBlockY();
                z2 = l2.getBlockZ();
               
                getConfig().set(x2 + " " + y2 + " " + z2, "Spawn2 ");
                saveConfig();
               
                p.sendMessage("Suradnice su : " + l2.getBlockX() + " " + l2.getBlockY() + " " + l2.getBlockZ());
               
               
                if(cmd.getName().equalsIgnoreCase("getx2")) {
                    getConfig().getInt("", x2);
                   
                    p.sendMessage("X2 je : " + getConfig().getInt(x2));
                }
            }
           
        }
       
        return true;   
       
    }
