Newlines in Config?

Is there any way to have newlines to config? Sorry for being vauge..... Here is my code:

Code:

public class CommandExecutorClass implements CommandExecutor{
    public Blocktionary plugin;
     
    public CommandExecutorClass(Blocktionary plugin){
            this.plugin = plugin;
    }
    @Override
    public boolean onCommand(CommandSender sender, Command command,String label, String[] args) {
        if (sender instanceof Player) {
              Player player = (Player) sender;
              if (command.getName().equalsIgnoreCase("buildspawn")){
                  Location loc = player.getLocation();
                  FileConfiguration config = plugin.getConfig();
                  config.set("Loc.world" , loc.getWorld().getName());
                  config.set("Loc.x" , loc.getX());
                  config.set("Loc.y" , loc.getY());
                  config.set("Loc.z" , loc.getZ());;
                  plugin.saveConfig();
                  sender.sendMessage("Set builder spawnpoint to §6 X: "+loc.getX()+" Y: "+loc.getY()+" Z: "+loc.getZ()+"§f in world §6" + loc.getWorld().getName());
              }
            } else {
              sender.sendMessage("Only players can run this command!");
              return false;
            }
            return false;
    }
 
}
