Delete files in Java, delete directories and all files under directory

File.delete () can only be used to delete "a file or empty directory"! So to delete a directory and all the files and subdirectories in it, recursively delete the code example as follows:

     Public void Deleteallfilesofdir (File path) {          if (!  Path.exists ())              return;           if (Path.isfile ()) {              path.delete ();               return ;          }           = path.listfiles ();            for (int i = 0; i < files.length; i++) {              deleteallfilesofdir (files[i]);          }          Path.delete ();      }
