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'm trying to extend a Java Swing component in Clojure, i.e. I want to extend a javax.swing.JComponent and add some custom methods implemented in pure Clojure in addition to all the standard inherited methods.
I've tried using "proxy" which works great if I just want a single instance (in the same way as an anonymous inner class). However I'd really like a named class so that I can generate an arbitrary number of instances.
What's the recommended way of doing this?

I read a lot of blogs and see people all the time talking about bad things in the java programming language; a lot of them are about annotations and generics that were added to the language in 1.5 release.

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.
