Do we have a method or way to find out a JDialog instance is already disposed or not.

`isVisible`? `isDisplayable`? – MadProgrammer Sep 10 '15 at 06:16
Yes.But some times JDialog call dispose many times.Some dialog call it when closing it.So if we call GC it will call again.Problem is we keep a log of disposed dialogs.It is a text file.Some dialog log more that one.So need to avoid logging if dispose already called. – Prabhath Sep 10 '15 at 06:23
It seems to me that this is a form of premature optimization. If you're worried about dialogs, keep a reference to a small number of dialogs and change their content as needed. But I would only worry about it if the app. was throwing an `OutOfMemoryError` and even then, I'd be looking at other areas of the app. first. – Andrew Thompson Sep 10 '15 at 06:27
