Introduction to Java 11 Standarized HTTP Client APIThe HTTP Client API is now part of the Java SE 11 standard. The module name and the package name of the standard API is java.net.http. The API provides high-level client interfaces to HTTP (versions 1.1 and 2) and low-level client interfaces to WebSocket.
Multiple Requests Using HTTP/1.1 VS HTTP/2The Java HTTP Client supports both HTTP/1.1 and HTTP/2. By default the client will send requests using HTTP/2. Requests sent to servers that do not yet support HTTP/2 will automatically be downgraded to HTTP/1.1
