How to I make a Targetable Command?

I want to make a fake OP plugin but I cannot figure out how to make a command in this form "/fakeop {name}" So far, I got it up to here.

All I want this to do is be target able.

Code:

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {

        if (!(sender instanceof Player)) {
            sender.sendMessage("You must be a player to use this command!");
            return false;
  

        }
      
                Player player = (Player) sender;
                player.sendMessage(ChatColor.GRAY + "" + ChatColor.ITALIC + "[Server: Opped " + player.getName() + "]");
                player.sendMessage(ChatColor.YELLOW + "You have been oped!");
                player.playSound(player.getLocation(), Sound.WITHER_DEATH, 2F, 1F);
                return true;
          
    }

      
      
               }

 

I'm sorry. I am still pretty new to this. Can you explain what you mean by "Check if args > 0"?

 

I'm very sorry, I cannot find anywhere in my code where i put a args > 0.

Nvm! I figured out my issue. I never even thought of adding a target. Thanks for helping me!

That's because he's telling you to put it in.
