Hello jabber, i tried ur above codes.when i compiled the "user-friendly" version, there was an Error message for statement System.exit(); ---
exit(int) in java.lang.System cannot be applied to ()
I tried different int in the braces and all of them worked well, but i don't know what the paremeter means here..

thanx jabberit's difficult for me to teach myself since my only programming experience is the simplest BASIC programming when i was in elementary school and foundamental javascript i'm learning in the class now. i always stuck into the mud of those trifles and the progress is slow. Anyway i have time.
This forum is really helpful. i always check some old posts over and over no matter whether i can understand what u guys are talking about. i'm happy that i can understand more and more now.

the result is right,because you use "args[0].toUpperCase()".but when you run the program,you don't append a parameter,so args[0] == null,
call null.toUpperCase will generate null exception.
