AwsCredentials credentials = AwsBasicCredentials.create("accessKeyId", "secretAccessKey");
S3Client s3Client = S3Client.builder()

                .build();

CreateBucketRequest createBucketRequest = CreateBucketRequest.builder()

                .build();
s3Client.createBucket(createBucketRequest);

ResponseInputStream<GetObjectResponse> response = s3Client.getObject(getObjectRequest);
response.transferTo(new FileOutputStream("path/to/save/file"));
