Solved Commands not running/showing in the console

I am knew to programming in java (but not programming in general) so I thought I'd attempt to make a plugin where you can do /donate <rank> and it shows you the information about that rank. So far I've managed to get the plugin to show some text when no args are given, but when args are given, nothing happens. When /donate is run by the console without args a message shows as I've coded, when run with args nothing happens or shows. When a player runs /donate with or without args nothing is shown in the console to show it has been run.
Note this plugin was compiled with the tekkit version of craft bukkit, but the code is so basic I doubt that matters too much?

here is the code: http://pastebin.com/N2AmTQQe

The code is most likely really messy and inefficient so sorry if it's hard to read.

Dont use == for strings, use equals() or equalsIgnoreCase() If it does not matter what case it is(so that ...
/donate DoNaToR
...should work)

 

Thanks for the help. I forgot about that line.

 

@cheekycharlie101
Is it solved? If so, mark the thread as solved

 

Done.
