In today’s world of web services and IoT, JSON has become the go-to protocol to carry information from the client to the server. They have replaced XML as the most preferred way to transfer information in a platform-independent way.

Unfortunately, JDK doesn’t have a JSON library. But, there are many good third-party libraries that allow you to both parse and create JSON messages, like Jackson and Gson.

A Java web developer should be familiar with at least one of these libraries. If you want to know more about Jackson and JSON, I suggest going through JSON with the Java API course from Udemy.
