 Your label has to be inside another component (a container) to be visible.
Changing a local variable will never work. Even changing an instance field 
won't work unless you've specially defined your own component somehow. Most 
Swing components are also containers. However normally you use JFrame and 
JPanel as your containers. Call the add method, or use the GUI layout tool to 
just drag and drop components onto one.

Does anyone have a simple working project of this:

(1) It has a form with a JPanel dragged from the swing control palette, (2) In 
the JPanel a Jlabel is dragged from the swing control palette. (3) The jlabel 
is set to invisible at the start of the project. (4) The project becomes 
visible when a button is pressed. (5) The project becomes invisible when a 
button is pressed.
