        String line;
        while ((line = in.readLine()) != null ) {
            response.append(line);
        }
        in.close();
        return response.toString();
    } catch (IOException e) {
        throw new IllegalStateException( "Something is wrong: " , e);
    }
}

以下语句可用于以异步方式运行该方法。

final CompletableFuture<String> jokeAsync = CompletableFuture.supplyAsync(() -> getChuckNorrisJoke());

尽管我认为我理解CompletionStage与 的关系CompletableFuture，但我不确定如何使用它CompletionStage来完成相同的任务。

final CompletionStage<String> jokeAsync = …
