如何使用Java接口和SoftLayer客户端删除子网？

import com.softlayer.api.ApiClient;
import com.softlayer.api.RestApiClient;
import com.softlayer.api.service.network.Subnet;

public class SubnetDeletionExample {
    public static void main(String[] args) {
        // SoftLayer API凭据
        String username = "YOUR_USERNAME";
        String apiKey = "YOUR_API_KEY";

        // 创建SoftLayer客户端实例
        ApiClient client = new RestApiClient().withCredentials(username, apiKey);

        // 子网ID
        int subnetId = 1234567;

        try {
            // 获取子网对象
            Subnet subnet = Subnet.service(client).getObject(subnetId);

            if (subnet != null) {
                // 删除子网
                Subnet.service(client).deleteObject(subnetId);
                System.out.println("子网删除成功！");
            } else {
                System.out.println("未找到指定的子网！");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
