My Problem is that when i tip "#ban" in the chat. There arrives a big error message.
I want that when i tip this, that i get a Message in the chat, like "Usage: #ban <PlayerName>" .

Code::

Code:

    @SuppressWarnings("deprecation")
    @EventHandler
   
    public void onBanCMD(AsyncPlayerChatEvent e) {
        Player p = e.getPlayer();
        String[] args = e.getMessage().split(" ");
        Player t = Bukkit.getPlayer(args[1]);
       
            if(args[0].equalsIgnoreCase("#ban")) {
                e.setCancelled(true);     
               
               
               
                if(t != null) {
                    p.sendMessage(pr+"§9"+args[1]+" §awurde gebannt!");
                    t.kickPlayer("§c§lDu wurdest gebannt!");
                    t.setBanned(true);
                }else {
                    p.sendMessage(pr+"§9"+args[1]+" §cist nicht Online!");
                }
               
           
            }
       
        }

Thanks for Reading this. I Hope you can help me out

 

Why would you not use commands for this?
But if you must do it this way, you can surround the whole thing in a try-catch block.

 

ok thanks i got it
