Idiom for Swing apps with the "new" thread-safety concern?

Hello.

I have decided to look again at Java after a *really* long break. While
browsing through the Swing tutorials [1], I noticed that the basic
skeleton of the demo applications had something new. There is now a
concern with thread-safety which is illustrated by the use of the
SwingUtilities. invokeLater() method for the GUI manipulation code.

In the demos, the private static method which is responsible for setting
up the GUI (createAndShowG UI) uses local instances in order to create
the main window and other Swing components as opposed to having the user
class actually extend JFrame and contain references to its child
components (JLabel, JButton, etc.). Is this how it should be done now?
What about having easy access to the frame's components? In case
extending from JFrame is still a current practice, could anyone describe
the idiom for it, if any? In other words, what would a basic Swing
application with a user class extending JFrame and the thread-safety
concern in place look like?

Thank you,

Can anyone explain to me a meningfull use of the "new" keyword (Shadows in VB). I think i understand how it works fully but i cant figure out why you would use it. Why would you want to declare a variable in a derived class with the same name as in the base class but with a diffrent meaning? Anyone can think of a scenario for this?

I need VB.NET's "shadows" functionality inside a C# project. I tried the "new" keyword, but it didn't seem to work, because my particular function does in fact differ in signature to the function that is being hidden in the base class. In VB.NET, the shadows keyword hides all the inherited functions, regardless of signature. I need this functionality in C#.

I'm just learning C#. I'm writing a program (using Visual C# 2005 on WinXP) to combine several files into one (HKSplit is a popular freeware program that does this, but it requires all input and output to be within one directory, and I want to be able to combine files from different directories into another directory of my choice). My program seems to work fine, but I'm wondering about this loop: for (int i = 0; i < numFiles; i++)

I have never used one in personal or professional C++ programming. Am I a holdover to days gone by?
