From source file:com.yoshio3.services.StorageService.java

public void deleteAll(String containerName) {
    try {/*from  ww  w.  j  a  va  2  s.  com*/
        CloudBlobContainer container = blobClient.getContainerReference(containerName);
        Iterable<ListBlobItem> items = container.listBlobs();
        Spliterator<ListBlobItem> spliterator = items.spliterator();
        Stream<ListBlobItem> stream = StreamSupport.stream(spliterator, false);

        stream.filter(item -> item instanceof CloudBlob).map(item -> (CloudBlob) item).forEach(blob -> {
