I am developing an application where it works with schedules, the user will leave the problem running and will continue using the pc normally and when a certain time will play a sound (already being done) and a dialog box would appear warning about the time. But I wanted this screen to be in the foreground, to appear on the user screen without having to click on the application.
Example: when I clicked on the swing button it would start the "conta()". After the loop is inside that "conta()", if finished it will appear the dialog box. I just want this box to appear on the user screen even though the application is MINIMIZED, in case you don’t need to click on your application to see the message, it will just appear to you, without having to go to it, you understand?
For example, I leave this application running after clicking the button and I will use something else on the pc (and it is minimized), and when it was to appear the dialog box it would show on the normal screen, without needing to maximize the application.

JOptionPane.showMessageDialog (null, "Texto da mensagem", "titulo", JOptionPane.INFORMATION_MESSAGE);doesn’t solve?– user28595
No, I need to open the application again, just like this to visualize. I would like it to appear without needing to go directly to see if there are any messages, it would simply appear on the screen.

Then add a [mcve] of your application so it is possible to view the problem.

Actually you don’t even need the code, but here’s the thing, for example, I let this one run, it will take a while to finish, and when (imagine that this is a swing, that when I click on a button it starts the loop), after that I would minimize the screen and use the pc normally, i wanted the dialog to appear on my screen without me having to click on the application (which is minimized) to see understand?
– Hamon Córdova
Without seeing the code becomes complicated to suggest something, the question would be wide and could be closed, because there are several ways to do this. It would be interesting to add an example that can be played, from the screen where you want to do this.
– user28595
Okay, it’s edited. I’m learning to deal with it here. If you can try again to help me with the main question, I’d appreciate it.
– Hamon Córdova
I tested the code with the minimized screen and the message box appeared even with the window being minimized. Joptionpane always appears in the foreground.
– user28595
Okay, try it this way now. Click on the button and then click on another icon, for example from the browser (without clicking to minimize), you will see that now does not appear.
– Hamon Córdova
Can help me even diegofm?
– Hamon Córdova
I’m doing some tests, just a moment and I’ve already put a solution.
– user28595
Okay, thank you very much!
