You are using "setVisible" with AWT FileDialog, maybe you should use some
"show" or similar method instead

Actually setVisible(boolean) is the method to use. show()/hide() is deprecated and called by setVisible.

Common misconception. Component.show() is deprecated, as it's considered to be setting a property on the component, much like location, size, etc., and won't actually show it unless the parent window is shown.

Window.show() (including Dialog.show() and Frame.show()) is NOT deprecated. This does much more than simply set a property and return. In the case of a modal dialog for example it blocks until the user closes the dialog. Quite some side effect for a simple set() method :-)

You're right, it doesn't matter which you call as one calls the other, but as a matter of style I think it's preferable to call show() on windows (and it's setVisible that should be deprecated), otherwise you risk obscuring the fact that you're actually performing a fairly substantial action in that call. (Consider: most properties on a component, such as their font, colour, etc. and even their visibility can safely be left with their default values and they will be usable, but that clearly doesn't apply when calling setVisible on a window).
