Solved Problem with custom /ban plugin

I get this messy error when i do /ban without any args (it should print "Please specify a player" as i have "if(args.length == 0) { sender.sendMessage();}").

                return true;
            }
            String msg = "";
            for(int i = 1; i < args.length; i++){
                msg += args[i] + " ";
            }
            t.kickPlayer(ChatColor.GRAY + "You have been banned for " + msg);
            t.setBanned(true);
            return true;
 
 
        }
 
 
 
 
 
        return true;
    }
 
}
[/i]

 

You're trying to get a Player with args[0] before the length of args is checked..
