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.)
Hi
I'm new to java.
I'm trying to use some dynamically loaded classes in my application.
The application doesn't know classes , Just it try to load a class by name that its name came from input.
It doesn't know class (So I can't use casting) but just needs to call some methods of that class (every class should have that methods).
I thought about interfaces but I don't know how.
How can I call those methods?
Thanks
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'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.

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.
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?
Do you know a good guide for Java, such as "dive into python" for python?
If I searched google I expect I would find tons of random guides, but trying them all until I found a good one could take ages... that's why I am asking: do you already know one in particular? one you KNOW is good?
I already know C, PHP and a bit of Python, if that matters.
