class Main{
    //we can use class HttpClient 
    //https://www.youtube.com/watch?v=5MmlRZZxTqk

    public static void main(String args[]) throws IOException, InterruptedException {    
        HttpClient client = HttpClient.newHttpClient();
        HttpRequest request = HttpRequest.newBuilder()
        // .GET() this line is optional because it is default
        .header("accept","application/json")
        .uri(URI.create("https://whatever.com"))
        .build();
        HttpResponse<String> response = client.send(request, BodyHandlers.ofString());
        System.out.println(response.statusCode());
        System.out.println(response.body()); 
        System.out.println(response.getClass().getName());
    }
}

所以我读了BodyHandlers.ofString（）方法的文档，我的理解是它会把响应变量的值解析成一个字符串。

System.out.println(response.getClass().getName());

结果是jdk.internal.net.http.HttpResponseImpl？我读到另一篇文章说，永远不要在idk.internal.* 中使用任何类，那么我做错了什么吗？
