Contoh kode berikut menunjukkan cara untuk mulai menggunakan AWS Key Management Service.

#### [ Java ]

**SDK untuk Java 2.x**  
 Ada lebih banyak tentang GitHub. Temukan contoh lengkapnya dan pelajari cara mengatur dan menjalankannya di [Repositori Contoh Kode AWS](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javav2/example_code/kms#code-examples).

import software.amazon.awssdk.services.kms.paginators.ListKeysPublisher;
import java.util.concurrent.CompletableFuture;

        /*
         * The `subscribe` method is required when using paginator methods in the AWS SDK
         * because paginator methods return an instance of a `ListKeysPublisher`, which is
         * based on a reactive stream. This allows asynchronous retrieval of paginated
         * results as they become available. By subscribing to the stream, we can process
         * each page of results as they are emitted.
