How to Programmatically Trigger JFrame's Close Button Behavior
In contrast to the default close operation set by setDefaultCloseOperation, you seek to replicate the behavior triggered by clicking the X close button or pressing Alt F4 (on Windows).
Dispatching a Window Closing Event
To emulate the X close button's action, the solution lies in dispatching a window closing event to the JFrame. The ExitAction from the Closing An Application class offers a convenient way to achieve this.
Usage
To invoke the desired behavior, utilize the following code snippet:
frame.dispatchEvent(new WindowEvent(frame, WindowEvent.WINDOW_CLOSING));
