  ProjectGlobalHttpsHealthCheckName httpsHealthCheck = ProjectGlobalHttpsHealthCheckName.of("[PROJECT]", "[HTTPS_HEALTH_CHECK]");
  HttpsHealthCheck2 httpsHealthCheckResource = HttpsHealthCheck2.newBuilder().build();

  @param httpsHealthCheck Name of the HttpsHealthCheck resource to update.
  @param httpsHealthCheckResource An HttpsHealthCheck resource. This resource defines a template
  for how individual instances should be checked for health, via HTTPS.
  @param fieldMask The fields that should be serialized (even if they have empty values). If the
  containing message object has a non-null fieldmask, then all the fields in the field mask
  (and only those fields in the field mask) will be serialized. If the containing object does
  not have a fieldmask, then only non-empty fields will be serialized.
  @throws com.google.api.gax.rpc.ApiException if the remote call fails
