# Zona Penggunaan Wilayah AWS dan Ketersediaan
<a name="examples-ec2-regions-zones"></a>

## Menjelaskan Wilayah
<a name="describe-regions"></a>

Untuk mencantumkan Wilayah yang tersedia untuk akun Anda, hubungi metode Ec2Client. `describeRegions` Ini mengembalikan a [DescribeRegionsResponse](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/DescribeRegionsResponse.html). Panggil `regions` metode objek yang dikembalikan untuk mendapatkan daftar objek [Region](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/Region.html) yang mewakili setiap Region.

## Jelaskan zona ketersediaan
<a name="describe-availability-zones"></a>

Untuk mencantumkan setiap Availability Zone yang tersedia untuk akun Anda, hubungi metode Ec2Client. `describeAvailabilityZones` Ini mengembalikan a [DescribeAvailabilityZonesResponse](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/DescribeAvailabilityZonesResponse.html). Panggil `availabilityZones` metodenya untuk mendapatkan daftar [AvailabilityZone](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/AvailabilityZone.html)objek yang mewakili setiap Availability Zone.

 **Impor** 

```
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.ec2.Ec2AsyncClient;
import software.amazon.awssdk.services.ec2.model.DescribeRegionsResponse;
import software.amazon.awssdk.services.ec2.model.DescribeAvailabilityZonesResponse;
import java.util.concurrent.CompletableFuture;
```

 **Kode** 

Buat Ec2Client.

```
        Ec2AsyncClient ec2AsyncClient = Ec2AsyncClient.builder()
            .region(Region.US_EAST_1)
            .build();
```

Kemudian panggil describeAvailabilityZones () dan ambil hasilnya.

## Jelaskan akun
<a name="describe-accounts"></a>

Untuk membuat daftar informasi EC2 terkait tentang akun Anda, hubungi metode Ec2Client. `describeAccountAttributes` Metode ini mengembalikan [DescribeAccountAttributesResponse](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/DescribeAccountAttributesResponse.html)objek. Memanggil `accountAttributes` metode objek ini untuk mendapatkan daftar [AccountAttribute](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/AccountAttribute.html)objek. Anda dapat mengulangi melalui daftar untuk mengambil objek`AccountAttribute`.

Anda bisa mendapatkan nilai atribut akun Anda dengan menjalankan `attributeValues` metode `AccountAttribute` objek. Metode ini mengembalikan daftar [AccountAttributeValue](https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/ec2/model/AccountAttributeValue.html)objek. Anda dapat mengulangi melalui daftar kedua ini untuk menampilkan nilai atribut (lihat contoh kode berikut).
