HTTP/2 Server Push Via Java 11 HTTP Client API

Do you remember HttpUrlConnection? Well, JDK 11 has reinvented this API as the HTTP Client API. 

Do you remember HttpUrlConnection? Well, JDK 11 comes up with the HTTP Client API as a reinvention of HttpUrlConnection. The HTTP Client API is easy to use and supports HTTP/2 (default) and HTTP/1.1. For backward compatibility, the HTTP Client API will automatically downgrade from HTTP/2 to HTTP 1.1 when the server doesn't support HTTP/2.

Moreover, the HTTP Client API supports synchronous and asynchronous programming models and relies on streams to transfer data (reactive streams). It also supports the WebSocket protocol, which is used in real-time web applications to provide client-server communication with low message overhead.
