Topic: anybody know java?

[B]

im sittin here in computer science class, workin on some program which does nothing and not doin too well on it...just wondering who else out there knows java, or c++, basic, html,  or whatever other programming languages there are

[DaryanLenz]

I know a bit of java...system, out void main..blah, blah.  I hated it, but I could maybe help with basic stuff.

i pretty familiar and took the same class, i can try to help you out.  Whats the problem?

[scb]

what's the assignment?

[B]

well, theres a website with the instructions on it, but you cant access it out of the baltimore county public schools network, so ill do the best to explain it.
we're supposed to be writing a program which prompts to the user and inputs the length and width for a rectangle - setting those as the variables for the dimensions.  then it prompts to the user and asks for a degree amount and dimensional decrease. it takes those variables and displays lots of other rectangles, which are stationary, rotated around a central point, getting smaller and smaller as they go along...i dont really expect any help, but thanks, guys

shit, I took C 2 quarters ago and forgot all that shit, sorry for the non-help, but I sympathize, +

[MattD]

The link would help :-p

[Sean Gallemore]

COBOL

Man, that's about as useful as my Fortran and Modula-2 stuff I took in college. ;-)

this country's securities transactions rely HEAVILY on cobol.  it sucks, but wow, it's still WIDELY used

i got it all under control - i figured it out and turned it in today...here it is if anybody wants to see it
