I need to use the logic contained in some java classes. I found JNI, but that project seems not updated recently.
Is there a way to use it in a Delphi native application? I use Delphi 2009.
Is it possible to initialise an array in Java using the 'advanced' for loop?
e.g.
Integer[ ] numbers = new Integer[20];
int counter = 0;
for ( Integer i : numbers )
{
i = counter++;
}
for ( Integer i : numbers )
{
System.out.println(i);
}
This prints all nulls, why is that?
I'd like to merge 2 XML streams (strings) in Java, necessarily by XSLT (that I could change the transformation), but the problem is that the XMLs come as a string. There are many examples, but through the files.
Can this be done without saving them in files?
Thanks.
Is it to possible to capitalize the letters in a Textfield as they are being typed by the user in Java?
E.g. The user would type 'hello' and 'HELLO' would appear in the Textfield.
(Odd request and I don't like the idea either.)
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
I am developing an image editing app, so want to display an image selected by JFileChooser, so what would be best approach so that it can display all formats jpg, png, gif etc. OpenButton is used for invocation of filechooser.

}
catch (Exception e1) {
e.printStackTrace();
}
}
}

I have an iPhone application and I am porting it over to Android.
I have a service/controller that spawns new threads to perform some network tasks.

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.
I'm looking for an example of a java desktop application that consumes a Two-way SSL secured web service. Any tutorials or examples would be great, especially if they are based on the Eclipse IDE.
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?
Is it possible to create a simple server in Java that returns a response based on a given key?
So it would be a simple program, that stores a hashmap and returns the result based on a key provided by the client.
What would be the fasted implementation, to have it over HTTP or a socket? The client will be a web based application.

How do I refresh the data in the ResultSet to reflect the current data in the database?
Thanks!
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 am new to regular expressions. I want to use java's replaceAll() function to replace any CSS comments in a string.
Basically I want to use regex to search for anything that is surrounded by "/*" and "*/" and replace it with "".
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:
public static void main(String[] args)
{
EventQueue.invokeLater(new Runnable()
{
public void run()
{
new JFrame().setVisible(true);
}
});
}
Why? Are there any advantages?
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?
Greetings All,
Is there a way to expand the Java memory-mapped byte buffer such that the new size is reflected back to the mapped file on disk ?
