I tried setting JLabel on being visible only after I select a certain RadioButton. The programm is getting an error if I set lblNewLabel_1.setVisible(true) in the action performed of a radiobutton. It worked with the textField, but with this not. What can I do? Is it different with the JLabel? Is there any advice someone can offer me?

          It's because your label is declared in function context, put the declaration next the textbox declaration and it should work fine

          • I did not manage to do that. I declared JLabel lblNewLabel_1 at the top of the declarations and I still get the error. Can you be more specific please? It would be very helpful. Thank you
