Java version for the same ( using the new v12 SDK )

This uses the Shared Key Credential authorization, which is the account access key.

StorageSharedKeyCredential credential = new StorageSharedKeyCredential(accountName, accountKey);
String endpoint = String.format(Locale.ROOT, "https://%s.blob.core.windows.net", accountName);
BlobServiceClient storageClient = new BlobServiceClientBuilder().credential(credential)
                                      .endpoint(endpoint).buildClient();

BlobContainerClient container = storageClient.getBlobContainerClient(containerName)
if ( container.exists() ) {
   // perform operation when container exists 
}
