How to delete all folders (with files laid out in them) and files from a folder?

Question

Java

The context is the following: there is one folder. It contains several files, as well as several folders in which, in turn, there are several files.
How can I completely empty this folder?
At the moment I tried to implement it through the following code:

recursiveDelete(new File("C:/ProgramData/Ex"));

    public static void recursiveDelete(File file) throws NullPointerException {
        if (!file.exists())
            return;
        if (file.isDirectory()) {
            for (File f : file.listFiles()) {
                recursiveDelete(f);
            }
        }
        file.delete();
        System.out.println("Удаленный файл или папка: " + file.getAbsolutePath());
    }

But it only deletes some files, but does it not get about files in folders? How can this code be modified to clear the folder?

fandorin_official is the job you want to do for you or do you need to delete the directory recursively?
Class org.apache.commons.io.FileUtils

static void deleteDirectory(File directory)
Deletes a directory recursively.
