Try this:

InputStream inputStream = null;
ObjectMapper objectMapper = new ObjectMapper();
BlobClient blobClient = blobContainerClient.getBlobClient(fileName);
if(blobClient == null || !blobClient.exists()) {
    log.error("Blob not found or doesn't exist. Blob: {}", fileName);
    throw new IllegalStateException("Blob not found or doesn't exist");
}
try{
    inputStream = blobClient.openInputStream();
    byte[] content = inputStream.readAllBytes();
    return objectMapper.readValue(content, new TypeReference<>() { });
} catch (Exception e) {
    log.error("Error occurred while downloading or parsing the blob. Blob: {}, Error: {}", fileName, e.getMessage());
    log.debug("Stack trace: ", e);
    //throw new custom exception;
} finally {
    if (inputStream != null) {
        try {
            inputStream.close();
        } catch (IOException e) {
            log.error("Error occurred while closing InputStream for Blob: {}. Error: {}", fileName, e.getMessage());
            log.debug("Stack trace: ", e);
            //throw new custom exception;
        }
    }
}

I got the solution for my problem. Here is the code.

BufferedReader br = new BufferedReader(new InputStreamReader(blob.openInputStream()));
String line;
while ((line = br.readLine()) != null) {
    System.out.println(line);
}

It may help someone.

I would suggest perhaps starting with: http://azure.microsoft.com/en-us/documentation/articles/storage-java-how-to-use-blob-storage/

From there you'll find a deeper link on "How to: Download a Blob". This should hopefully get you where you need to go.
