Examples of Enabling Bucket Versioning

This section provides examples of enabling versioning on a bucket. The examples first enable versioning on a bucket and then retrieve versioning status. For an introduction, see Using Versioning.

Using the Amazon S3 Console

For more information about enabling versioning on a bucket using the Amazon S3 console, see Enable Versioning in the Amazon Simple Storage Service Console User Guide.

Using the AWS SDK for Java

For instructions on how to create and test a working sample, see Testing the Java Code Examples.
