### Question:
UsersApi { public PostUsersResponse create(PostUsersRequest body) throws ApiException { ApiResponse<PostUsersResponse> resp = createWithHttpInfo(body); return resp.getData(); } UsersApi();  UsersApi(ApiClient apiClient); ApiClient getApiClient(); void setApiClient(ApiClient apiClient); com.squareup.okhttp.Call createCall(PostUsersRequest body, final ProgressResponseBody.ProgressListener progressListener, final ProgressRequestBody.ProgressRequestListener progressRequestListener); PostUsersResponse create(PostUsersRequest body); ApiResponse<PostUsersResponse> createWithHttpInfo(PostUsersRequest body); com.squareup.okhttp.Call createAsync(PostUsersRequest body, final ApiCallback<PostUsersResponse> callback); com.squareup.okhttp.Call deleteCall(Long userId, final ProgressResponseBody.ProgressListener progressListener, final ProgressRequestBody.ProgressRequestListener progressRequestListener); DeleteUsersUserIdResponse delete(Long userId); ApiResponse<DeleteUsersUserIdResponse> deleteWithHttpInfo(Long userId); com.squareup.okhttp.Call deleteAsync(Long userId, final ApiCallback<DeleteUsersUserIdResponse> callback); com.squareup.okhttp.Call retrieveAllCall(final ProgressResponseBody.ProgressListener progressListener, final ProgressRequestBody.ProgressRequestListener progressRequestListener); List<GetUsersResponse> retrieveAll(); ApiResponse<List<GetUsersResponse>> retrieveAllWithHttpInfo(); com.squareup.okhttp.Call retrieveAllAsync(final ApiCallback<List<GetUsersResponse>> callback); com.squareup.okhttp.Call retrieveOneCall(Long userId, final ProgressResponseBody.ProgressListener progressListener, final ProgressRequestBody.ProgressRequestListener progressRequestListener); GetUsersUserIdResponse retrieveOne(Long userId); ApiResponse<GetUsersUserIdResponse> retrieveOneWithHttpInfo(Long userId); com.squareup.okhttp.Call retrieveOneAsync(Long userId, final ApiCallback<GetUsersUserIdResponse> callback); com.squareup.okhttp.Call templateCall(final ProgressResponseBody.ProgressListener progressListener, final ProgressRequestBody.ProgressRequestListener progressRequestListener); GetUsersTemplateResponse template(); ApiResponse<GetUsersTemplateResponse> templateWithHttpInfo(); com.squareup.okhttp.Call templateAsync(final ApiCallback<GetUsersTemplateResponse> callback); com.squareup.okhttp.Call updateCall(Long userId, PutUsersUserIdRequest body, final ProgressResponseBody.ProgressListener progressListener, final ProgressRequestBody.ProgressRequestListener progressRequestListener); PutUsersUserIdResponse update(Long userId, PutUsersUserIdRequest body); ApiResponse<PutUsersUserIdResponse> updateWithHttpInfo(Long userId, PutUsersUserIdRequest body); com.squareup.okhttp.Call updateAsync(Long userId, PutUsersUserIdRequest body, final ApiCallback<PutUsersUserIdResponse> callback);  }### Answer:
@Test public void createTest() throws ApiException { PostUsersRequest body = null; PostUsersResponse response = api.create(body); }
