dee ♥ couch potatoes ..: preparing for java programming lab test .

here i am, steal some minutes after learns the java programming subject..

fiuhh, my head's heavy and dizzy but lazy in the same time when i try to remember all the things about java's coding.. fiuhh~ :')

actually i'm not really good at coding, i'm just good at design-ing with html.

and not really good to handle or make a really great programs through with java, vb.net, php or such as like them.. mine was so so... (@@')a

it's hendy's job! my job's only about design-ing, analyst and business!! hahaha. :DD

heyy yaa, i dunno whether you've know what major that i takes or not.

fyi, currently i'm taking Information System at Binus University, Jakarta, Indonesia. :)

anyway, if you don't mind i'm gonna spoil your monitor with these all java's codings, all was typed by myself through eclipse sdk 3.3.1 that's installed into my lappie... hehehe. :DD

*beware, maybe these all will make your head heavy as much as mine or maybe heavier than mine.. opps, sorry... (^^ ,)v
