good for you that don't have the answer to my question.
I am still patient!:)
thank you for your point. when I check if the frame is null it returns null but I can see that the frame is open and it is not closed. how is it possible?
but each of them that I use I get the following error;
"Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException"
I want to close a Frame automatically not by clicking the close button. I want it to be closed programmaticaly.
