public class PutVectorIndexSample {
    public static void main(String[] args) throws Exception {
        CredentialsProvider provider = new EnvironmentVariableCredentialsProvider();
        try (OSSVectorsClient client = OSSVectorsClient.newBuilder()

                .accountId("1234567890")

                    .dimension(3)
                    .distanceMetric("cosine")
                    .build();
            PutVectorIndexResult result = client.putVectorIndex(request);
            System.out.printf("status code: %d, request id: %s%n", result.statusCode(), result.requestId());
        }
