I have an image called "ball.jpg" and I want to program a code that
will find the color of a pixel at (20,20)

How do I find the color of a pixel using Java?
Please help!!

Hello guys, happy new year.
Well, a very basic question. I make a class objekt that lookes
something like this :

public class circle {

public static final PI = 3.14159;
public double r;
public double area(double r) {
return r*r*PI;
}
}

and then from somewhere else I do :

circle.r = 5;
double area = circle.area(); <--- this gives me a compilation error,
it wants me to specify circle.area(5). I thought

that it was legitamet code to leave it at (). Is'nt it what object
oriented code was all about, i have already defined the objects
variable r to bee 5, shouldent need to further specify
circle.area(5).
Thank you for any response in advance.

Tal como mencione en mi articulo anterior iReport es una herramienta
practica, visual y muy simple de utilizar para desarrollar reportes
utilizando el API de Jasper Report.

Los datos que vamos a mostrar en nuestros reportes pueden provenir de
distintos lugares tales como una base de datos o un archivo XML, estas
formas diferentes de obtener datos son las llamadas fuentes de datos -
Data Source.

Las fuentes de datos son representadas en Jasper Report por una
interfaz llamada JRDataSource, el motor ya provee muchas
implementaciones de esta interfaz para poder utilizar datos
provenientes de Arreglos, Vectores, Collections, Modelos de Tablas,
Consultas SQL, Cubos OLAP, Consultas JPA, Consultas Hibernate,
Archivos CVS, Documentos XML, por nombrar algunos.

Este artículo mostrará como utilizar iReport para manipular datos
provenientes de distintos orígenes, es decir que veremos como se usan
con iReport distintas fuentes de datos.

Has anyone developed a web app that creates subdomain names on the
fly? For example a users of our web service can create a subdomain on
our main domain name, such as customersusername.ourdomainname.com?

I'm just wondering how this could be done.

Thanks

I have a simple requirement at this point an Apple MAC OS X - that is
to detect the presence or lack of a USB device from java.

I have read about JSR 80, javax.usb, jUSB and all indicate not
available in Mac OS X.
I also know that in linux, I can do a "cat /proc/bus/usb/devices" and
get a list of devices connected to the machine.
Now Mac OS X is "linux" - yet there doesn't appear to be /proc/dev/...
etc.

Any suggestions on how to get the presence or lack of a USB device
from java on Mac OS X??

I tried to read files (gif) off of various websites, and I got a
security error each time. I can easily copy them by hand to my
computer. Does Java not have the ability to copy or read files from
the internet?

I'd like to tie a Java array to some code so when the array is
accessed my code gets run.

Is there some simple way to do this in Java?

This guy went out of his way to make it difficult to filter out his
spam. He realises you don't want to read it. Yet he persists anyway.

Why? All I can see is a vandalism motive, a desire to piss people
off.
