[URGRENT] Unhandled Exception Executing Command.

So I am trying to make a basic economy plugin for my server, when I type /economy it is meant to display "wrong arguments" but it keeps giving errors, also when players join it doesn't create a balance file for that player, I uploaded the command error as well as the eclipse project file so people can explore and fix, thank you, help fast please :3 !

Could you please post your Commands class? Also, take a look at line 20.

 

I posted a new thread with the download, also this was a mis-uploaded thread as I hadn't completed half the details >.<

 

Thiorum You can edit posts.

 

I couldn't see anything wrong with it, no errors.

 

Can you please post the class?

 

I don't like having commands that way...

You need to check your args, and by the way, arrays indexes start at 0. Learn Java please.

 

xTrollxDudex hrm I do it this way...
edit: oh and I was talking about his cmd. etc...

Code:java

 @Override
public void onEnable() {
getCommand("command").setExecutor(this);
PluginManager pm = this.getServer().getPluginManager();
pm.registerEvents(this, this);
 
}
 
 
 
public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
if (args.length == 0) {
//do something
}
if (args.length == 1) {
if (args[0].equalsIgnoreCase("check")) {
//do something
 
}
 
}
}

 

Bump, still need help >.<

 

You need to check the argument count FIRST.

 

what do you mean?

 

Code:java

if(args.length == 1){
//code
}

That would be if the command is:
/somecommand argument
and the word argument would be args[0]
Edit:
I'll explain a bit more. When you made the command, you only typed "/economy". You checked for args[1] before checking the args length. As you didn't have any arguments, you got the ArrrayIndexOutOfBoundsException. Also, in java, you start counting array indexes at 0, not 1. So if you have /economy something, the word something would be args[0].
