In java how do you delete the contents of a directory with out deleting the directory itself?

Question

Hi, I would like to know how in java you can delete all the files in a directory but keep the directory?

Many thanks

Answer 1

Oddly, I recently had to write a script to do just this because Windows doesn't have a command that will do this. I was working from the CMD shell, not using Java, because--sadly--there's no JDK installed most places I go.



The logic is the same, though. Loop through each file in the directory and delete it. If the file file is subdirectory, recursively call self on that subdirectory to delete it.



There's a simple example of this on The Java Developer's Amanac web page:

You can get a list of all the files in a directory and loop through them one at a time. Thats how I do it...

Answer 3

Probably in exactly the same way that you'd do so in any other country in the world.
