Deleting a bucket

The following Java example deletes a bucket that contains objects. The example deletes all objects, and then it deletes the bucket. The example works for buckets with or without versioning enabled.

For instructions on creating and testing a working sample, ssee Getting Started in the AWS SDK for Java Developer Guide.
