Programming Amazon S3 using the AWS SDK for Java AWS Documentation AWS SDK for Java. Amazon S3 Examples Using the AWS SDK for Java From there, you can download a single source file or clone the repository locally to get all the examples to build and run. HOW TO DOWNLOAD THE FILES FROM AWS S3 INTO LOCAL SYSTEM USING JAVA. First, create the object of AWSCredentials and pass the aws_access_key_id and aws_secret_access_key as parameters.
