The second to the last line is the problem.  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.

This might help:
