How to specify region name in AWS S3 Java API?

Question

I am using AWS Java API for S3. The access key, secret key, bucket name, and region name are all provided to my application as environment variables.

I am not sure how to set the region name...I'm currently getting the AmazonS3Client

return new AmazonS3Client(new BasicAWSCredentials(accessKey, secretKey))

Can someone please tell me how to set the region name?

Notice that if you have the region as a string, you can do this:

Regions regions = Regions.fromName('us-west-1');

And you can create a credentials provider in a variety of ways, including this:

AWSStaticCredentialsProvider credentialsProvider = new AWSStaticCredentialsProvider(

        new BasicAWSCredentials(ACCESS_KEY, SECRET_KEY));

and then (for whatever builder you're doing), you can do this:

AmazonSNS snsClient = AmazonSNSClientBuilder.standard()

    .withRegion(region)

    .withCredentials(credentialsProvider)

    .build();
