  <p>Sample code:
  
  <pre><code>
  try (NotificationChannelServiceClient notificationChannelServiceClient = NotificationChannelServiceClient.create()) {
  NotificationChannelName name = NotificationChannelName.of("[PROJECT]", "[NOTIFICATION_CHANNEL]");
  boolean force = false;
  notificationChannelServiceClient.deleteNotificationChannel(name, force);
  }
  </code></pre>
  
  @param name The channel for which to execute the request. The format is
  `projects/[PROJECT_ID]/notificationChannels/[CHANNEL_ID]`.
  @param force If true, the notification channel will be deleted regardless of its use in alert
  policies (the policies will be updated to remove the channel). If false, channels that are
  still referenced by an existing alerting policy will fail to be deleted in a delete
  operation.
  @throws com.google.api.gax.rpc.ApiException if the remote call fails
