How to keep JFrame active while looping in the main thread?

Question

Java

I want to make the application start unpacking the archive in a separate thread, but before that, a JFrame with a progress bar would appear. It would be fully active during unpacking, but at the same time, that code in the main thread will be executed after unpacking is completed (for this I want to use an infinite loop that will stop after unpacking is completed)
How can this be effectively, correctly implemented?

Answer 1

Usually you don't need to do an infinite loop for this. You can simply send events through property changes through actionListener. Read here - https://docs.oracle.com/javase/tutorial/uiswing/co...
If you have questions, ask.
Yes, you can leave the JFrame active, for example, by making it modal or by embedding a JDialog in it.
