How to delete the directory through java?

Question

I am creating folder within a folder from java. Whenever the data loads, the directory should be reloaded with the new data. My code is:

String ResultPath = System.getProperty("user.home") + "\\Desktop\\Report";
new File(ResultPath).mkdir();
new File(ResultPath + "\\images").mkdir();

I have used :

FileUtils.deleteDirectory(new File(ResultPath));

in the if else loop to execute the same, but it is not displaying the desired output.

@bub Reloading and deleting are different things. What does "whenever the data loads" actually mean? Which data? — nbro, Mar 21 '17 at 14:36
@nbro I think she means when she reads from the directory after creating the directory...but you are right, it is not 100% clear. — B001ᛦ, Mar 21 '17 at 14:38

I don't get what you actually meant but to delete a directory using Java 8 API :

if (Files.exists(path, LinkOption.NOFOLLOW_LINKS)) {
  Files.walk(path)
       .sorted(Comparator.reverseOrder())
       .map(Path::toFile)
       .forEach(File::delete);
}

Do not forget to put the LinkOption.NOFOLLOW_LINKS option to not follow symbolic links as this can be dangerous.
