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:
