How to delete all files and folders in one folder on Android

Question

I use this code to delete all files:

File root = new File("root path"); File[] Files = root.listFiles(); if(Files != null) {     int j;     for(j = 0; j < Files.length; j++) {         System.out.println(Files[j].getAbsolutePath());         System.out.println(Files[j].delete());     } } 

It will delete false where Files[j] is a folder.

I want to delete folder and all its sub files.
How can I modify this?

void deleteRecursive(File fileOrDirectory) {      if (fileOrDirectory.isDirectory())         for (File child : fileOrDirectory.listFiles())             deleteRecursive(child);      fileOrDirectory.delete();  }
