"https://expired.badssl.com" 有什么用？谁能给我解释一下

Question

我在我的代码中使用它如下。但不明白它有什么用。

URL url = new URL("https://expired.badssl.com/");//https://revoked.grc.com/
HttpsURLConnection urlConnection = (HttpsURLConnection)url.openConnection();
urlConnection.setHostnameVerifier(connection.getHostnameVerifier());
urlConnection.setSSLSocketFactory(connection.getSSLContext().getSocketFactory();

LineNumberReader lnr = 
   new LineNumberReader(new InputStreamReader(urlConnection.getInputStream()));

String line;
while (null != (line = lnr.readLine()))
   System.out.println(line);
