mkdir

[Roedy Green]

The docs don't talk about what happens in various situations where you
create a file when the directory it belongs to does not exist yet.

If this is a possibility, are you supposed to use mkdirs first?

The docs don't talk about what happens in various situations where
you create a file when the directory it belongs to does not exist
yet.

You get an IOException.

If this is a possibility, are you supposed to use mkdirs first?

Yes, if you want to enforce that the file can be written. However, if
you use a GUI file chooser, the user usually can create the directory
himself using the file chooser, so you can skip that code.
