Java 高效删除目录的方法 (可以避免栈溢出)

 public static boolean deleteFile(final File file) {
        try {
            if (null != file) {
                final LinkedList<File> dirLinkedList = new LinkedList<>();
                if (file.exists()) {
                    if (file.isFile()) {
                        file.delete();
                    } else if (file.isDirectory()) {
                        dirLinkedList.add(file);
                        for (int i = 0; i < dirLinkedList.size(); ++i) {
                            final File child = dirLinkedList.get(i);
                            final File[] items = child.listFiles();
                            if (null != items) {
                                for (final File item : items) {
                                    if (item.isFile()) {
                                        item.delete();
                                    } else if (item.isDirectory()) {

                                }
                            }

                }

            }
            return true;
        } catch (Exception e) {
            e.printStackTrace();
            return false;
