Summoning an armor stand and rotating it?

So I'm trying to create a trackless ride system so I don't have to use Minecarts but I have no idea how to start but I managed to get this

Code (open) Code (close)

Code:

@Override
    public boolean onCommand(CommandSender sender, Command cmd, String lable, String[] args) {
        Player player = (Player) sender;
        if(sender instanceof Player){
            Bukkit.getWorld("World").spawnEntity(Location, Armor_Stand)
            player.sendMessage(ChatColor.translateAlternateColorCodes('&', "&cDEV test started"));
        }
        else {
            sender.sendMessage("HEY! Only players can run this");
        }
        return true;
    }

All I want to know is how to rotate an armor stand and teleport it / move it. Hopefully, someone can link me to a wiki or something that explains how to do something similar to this

 

Please first check if the sender is a player before casting it!! For the armor stand, what did you tried already?

 

Yeah ill fix that player thing, and i tried
Bukkit.getWorld("World").spawnEntity(Location, Armor_Stand)
