Why use createAndShowGUI

Java

Greetings!

I fell upon this piece of code in the Oracle docs:

public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI(); 
            }
        });

Until now, instead of

createAndShowGUI

I was instructed to use

new

plus the name of the class. To build the GUI I would use a typical constructor.

But in the above example, the GUI is being built within a method which is called afterwards from the

run()

method.

So is there any diference? (The full code from the docs can be found in http://docs.oracle.com/javase/tutorial/uiswing/painting/step2.html[^])
