In the following article, I show you multiple examples of the library. You find examples of these features in the demo applications below. However, these missing features are no deal-breakers and can be implemented on top of the new HTTP client library, which speaks for the flexibility and configurability of the library. Especially the missing compression support surprised me a little bit coming from OkHttp, where the library transparently handles this functionality. I think there is still room for these libraries on Java 11 because, as you will see later, the new Java 11 HTTP client misses a few convenient functions like URI builder, multipart form data, form data, and compression support. Because of that, most projects added an external HTTP client library, like Apache HTTP Client and OkHttp to their projects. However, it's not the most straightforward API to work with and does not support the newer HTTP/2 protocol.

Up to Java version 11, the only built-in way to work with HTTP is URLConnection (available since Java 1.0). It's a way for the Java platform developers to release new features early, collect feedback from the developer community, and, when ready, release it officially, as they did with the HTTP client library. We may see more of this pattern in the future because of Java's shorter six-month release cycles. To be exact, the library was already part of Java 9 but only as an incubation module. It's one of the more significant new features we've got with Java 11. In this blog post, we will look at the HTTP client library introduced in Java 11 (September 2018). Take a look at this Java Code: Server Code – CrunchifyNIOServer.A closer look at the Java 11 HTTP Client Home | Send Feedback A closer look at the Java 11 HTTP Client

Iterate through ArrayList and send each companyName to server.

Create CrunchifyNIOClient.java which tries to connect to server on port 1111.

Once you get last company name “crunchify”.

if yes – read from buffer and print on Eclipse console.

use isReadable() to check if channel is ready for reading.

use isAcceptable() to check if channel is ready to accept a new socket connection.

Create CrunchifyNIOServer.java which opens connection on port 1111.

How to implement High-Performance I/O with Java NIO.What is the exact use of java nio package.What is Java NIO and Java NIO tutorials.If you have below questions then you are at right place:

selector may be created by invoking the open method of this class, which will use the system’s default selector provider to create a new selector.channels represent connections to entities that are capable of performing I/O operations, such as files and sockets defines selectors, for multiplexed, non-blocking I/O operations.In this tutorial we will go over and libraries. Starting JDK 1.4, NIO was created to allow all Java programmers to implement very high-speed input/output without having to deal with custom native code. NIO uses library compare to simple I/O which drains and fills back buffer internally any operating system.

I have been working with NIO since last 2 years and would like to share simple Server-Client code for my readers who are free to use this code in their production environment.
