What I'm trying to do is to get List<byte[]> from InputStream. I'm sending HTTP request to an API that returns List<byte[]> and I want to get that list from the content body.

HttpPost httpPost = new HttpPost(endPoint);
CloseableHttpClient httpclient = HttpClients.createDefault();
httpPost.setEntity(new ByteArrayEntity(ReqBody));
CloseableHttpResponse response = httpclient.execute(httpPost);
System.out.println(response.getStatusLine());
System.out.println(response.getEntity().getContentType());

return response.getEntity().getContent();

@Martin'sRun i want to get it as List not byte[] – mohanad joubeh Sep 28 '19 at 16:01
`List` means every element in the list is a byte array. How many elements will be in your list? What will the byte array in each element contain? – Abra Sep 28 '19 at 16:19
@Abra each element will be byte[] of protocol buffer object – mohanad joubeh Sep 29 '19 at 05:49
Are you using [Apache HTTP Client](http://hc.apache.org/) ? – Abra Sep 29 '19 at 10:46
@Abra yes Apache HTTP Client – mohanad joubeh Sep 29 '19 at 11:01
`java.io.InputStream` is an abstract class. From the last line of the code you posted, add a call to method `getClass()` to find the actual class. Maybe it's `ObjectInputStream`. In other words, what does `response.getEntity().getContent().getClass()` give you? – Abra Sep 29 '19 at 11:10
