My Java.app broadcasts a packet on the network as soon as it starts up. Everytime I start this app, the MAC asks me do I want to allow network connections blah..blah.. Can I use info.plist or something to allow network access to this app and not bother the user who has trustingly downloaded and installed my app.
Thanks

From what time I've spent with threads in Java, I've found these two ways to write threads.
public class ThreadA implements Runnable {
public void run() {
//Code
}
}
//with a "new Thread(threadA).start()" call
public class ThreadB extends Thread {
public ThreadB() {
super("ThreadB");
}
public void run() {
//Code
}
}
//with a "threadB.start()" call
Is there any significant difference in these two blocks of code?
In Java, is there any way to create an instance of any class that extends abstract class A, inside a member method of class A? Classes that extends abstract class A will return their instances with this method, but i don't want to implement same method in all subclasses with a "return this();" kind line.

Hi,
Does anyone know a library to compare addresses in Java ?
Something that would give equality on addresses, written in different ways.
For example, it should recognize that
"22 Acacia Avenue" and "22 acacia av."
is the same address.
Of course, this can escalate a lot, that's why i'm asking.
Thanks in advance.

I have a Java Swing project for my class. I would like put it on my website so people can use it. However I'm not sure if there is a way to turn it into a servlet. Or do I need to know JavaScript? I'm confused. Is there a way to make my swing application into a servlet automatically?
In Java, to create and show a new JFrame, I simply do this:
public static void main(String[] args)
{
new JFrame().setVisible(true);
}
However, I have seen many people doing it like this:

{
EventQueue.invokeLater(new Runnable()
{
public void run()
{
new JFrame().setVisible(true);
}
});
}
Why? Are there any advantages?
