Creating a bucket

The following example shows you how to create a bucket with a GUID at the end of the bucket name in US East (N. Virginia) Region (us-east-1;) by using the AWS SDK for Java. For information about other AWS SDKs, see Tools to Build on AWS.

import com.amazonaws.regions.Regions;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;
import com.amazonaws.services.s3.model.Bucket;
import com.amazonaws.services.s3.model.CreateBucketRequest;

import java.util.List;
import java.util.UUID;

public class CreateBucketWithUUID {
    public static void main(String[] args) {
        final AmazonS3 s3 = AmazonS3ClientBuilder.standard().withRegion(Regions.US_EAST_1).build();
        String bucketName = "amzn-s3-demo-bucket" +  UUID.randomUUID().toString().replace("-", "");
        CreateBucketRequest createRequest = new CreateBucketRequest(bucketName);
        System.out.println(bucketName);
        s3.createBucket(createRequest);
    }
}                

This example shows you how to create an Amazon S3 bucket using the AWS SDK for Java. For instructions on creating and testing a working sample, see Getting Started in the AWS SDK for Java Developer Guide.
