How do I refresh a GUI in Java?

Question

I have a general question that is Java related.

I am writing an application that has a GUI menu. I am trying to change one part of the GUI menu based on the selectio

Answer 1

..in my application the user select which device platform type they want top test (that choice is a set of two radio buttons on the left). When the user selects either Android or iOS, the center grouping of check boxes changes to reflect a group of android devices they can test or a group of iOS devices that they can test.

1. Put a panel in the 'center grouping'.
2. Use a CardLayout for the panel.
3. Add both iOS & Android controls to the panel with the card layout.
4. Flip between them as needed.
