Help with token plugin

Hi i'm trying to create a plugin that gives you tokens(custom currency) when you kill a player.
but it's not that i'm having issues with. I'm trying to create a command (/tokens add) i have the code working so it gives the player the tokens but i want it so when a user does /tokens add it displays the correct usage (e.g. "Usage: /tokens add <name> <amount>" but i have been getting internal error when attempting to preform the command.

Link to my current code: http://pastebin.com/6mULk2Nk

Thanks for reading.

If you can fix my code can you please put the entire code (with fix) in a pastebin and send me the link as i am a visual learner and will find it easier to understand and learn from. Thanks.

What i need help with: I need to make it so if a user doesn't specify a player(args[1]) or amount(args[2]) it displays the message "Usage: /tokens add <player> <name>".

Solution found!

Code:java

 
  if(args[0].equalsIgnoreCase("add")){
             if(args.length > 1){
                 Player t = Bukkit.getPlayer(args[1]);
                  if(t == null){
                        p.sendMessage("§3[§9Tokens§3]§f " + "Player can't be found!");
                        return true;
                    }
                    int value = Integer.parseInt(args[2]);
                    getConfig().set(t.getName() + ".money", getConfig().getInt(t.getName() + ".money") + value);
                    saveConfig();
                    p.sendMessage("§3[§9Tokens§3]§f " + value + " tokens have been given to " + t.getName());
                     } else {
             p.sendMessage("Usage: /tokens add <name> <amount>");
                     }
 
            }
 

What i was doing wrong:
Correct code:

Code:java

 
if(args.length > //Arg number(e.g. 0,1,2,3,4){
//code
}
 

Incorrect code:

Code:java

 
if(args[1].length() == 0){
//code
}
