Events with multiple JPanels and JButtons

[Oxnard]

I am trying to have 2 JPanels in one JFrame. The first JPanel (Panel1) has
two buttons. The second JPanel has a JTextField. The app works as expected
if I have only one button, but if I have a second button the second button
does not work. I found this example online and would like to expand it to be
able to use more than one button. What do I need to do to get the second
button to do a simple println? I have seen a number of posting but I am just
not quite getting it.

Thanks

What is 'expected'?

if I have only one button, but if I have a second button the second button
does not work.

Gets lazy does it? Have you tried flogging it with a whip?

You need to define.
- I expected this output.
- But got this ouput instead.
- The two differ by..

..I found this example online and would like to expand it to be
able to use more than one button. What do I need to do to get the second
button to do a simple println?

Suggestions:

Learn OO concepts and how to construct GUI's.

Start asking questions on a more appropriate group.

...and then when you have the hang of asking well framed
questions, move on to a more specific group.

..I have seen a number of posting but I am just
not quite getting it.

Looking at your code, it seems you have little idea of what you are doing.

Your example does not compile, and you could have made changes to
allow it to be an SSCCE*. I wrestled with it for ten minutes, but
it is not clear what you are trying to achieve, or why you subclassed
the JPanels, so I set it aside.
