StoreApi { public void deleteOrder(Long orderId) throws RestClientException { Object postBody = null; if (orderId == null) { throw new HttpClientErrorException(HttpStatus.BAD_REQUEST, "Missing the required parameter 'orderId' when calling deleteOrder"); } final Map<String, Object> uriVariables = new HashMap<String, Object>(); uriVariables.put("orderId", orderId); String path = UriComponentsBuilder.fromPath("/store/order/{orderId}").buildAndExpand(uriVariables).toUriString(); final MultiValueMap<String, String> queryParams = new LinkedMultiValueMap<String, String>(); final HttpHeaders headerParams = new HttpHeaders(); final MultiValueMap<String, Object> formParams = new LinkedMultiValueMap<String, Object>(); final String[] accepts = { "application/xml", "application/json" }; final List<MediaType> accept = apiClient.selectHeaderAccept(accepts); final String[] contentTypes = { }; final MediaType contentType = apiClient.selectHeaderContentType(contentTypes); String[] authNames = new String[] { }; ParameterizedTypeReference<Void> returnType = new ParameterizedTypeReference<Void>() {}; apiClient.invokeAPI(path, HttpMethod.DELETE, queryParams, postBody, headerParams, formParams, accept, contentType, authNames, returnType); } StoreApi(); @Autowired  StoreApi(ApiClient apiClient); ApiClient getApiClient(); void setApiClient(ApiClient apiClient); void deleteOrder(Long orderId); Map<String, Integer> getInventory(); Order getOrderById(Long orderId); Order placeOrder(Order body);  }### Answer:
