onCommand error

Hello,
I've a little problem with my Code
If I type /vote earn then I get an error.

Code:

    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
 
        if(!(sender instanceof Player)) {
            sender.sendMessage("This Command can only run by a Player");
            return true;
            }
        if(args.length == 0) {
            sender.sendMessage(ChatColor.GOLD + "== VOTE ==");
            sender.sendMessage("/vote earn 1");
            sender.sendMessage("/vote earn 2");
            sender.sendMessage("/vote earn 3");
            return true;
            }else{
                if(args[0].equalsIgnoreCase("earn")){
                    if(args[1].equalsIgnoreCase("1")){
                        sender.sendMessage("/vote earn 1");
                        return true;
                        }
                    else if(args[1].equalsIgnoreCase("2")){
                        sender.sendMessage("/vote earn 2");
                        return true;
                        }
                    else if(args[1].equalsIgnoreCase("3")){
                        sender.sendMessage("/vote earn 3");
                        return true;
                        }
                    }else{
                        sender.sendMessage(ChatColor.GOLD + "== VOTE ==");
                        sender.sendMessage("/vote earn 1");
                        sender.sendMessage("/vote earn 2");
                        sender.sendMessage("/vote earn 3");
                        return true;
                        }
                }
        return false;
        }

And the error

Code:

15:02:46 [SCHWERWIEGEND] null
org.bukkit.command.CommandException: Unhandled exception executing command 'vote

       at org.bukkit.command.PluginCommand.execute(PluginCommand.java:42)

It would help if you said WHAT error you get... >.<

 

How to read stack-traces, and troubleshoot your own plugins (by yourself)

 

Have add a check if there are 2 arguments now it's working

 

Yeah you were trying to check a value in an array that may not have existed.
