Java REST API Tutorial

In this tutorial, you will learn everything about REST and how to implement REST APIs (Restful web services) using Java.

What is REST?

The REST stands for REpresentational State Transfer
  •  State means data
  •  REpresentational means formats (such as XML, JSON, YAML, HTML, etc)
  •  Transfer means carrying data between consumer and provider using the HTTP protocol
A REST API is an intermediary Application Programming Interface that enables two applications to communicate with each other over HTTP, much like how servers communicate to browsers.

The REST architectural style has quickly become very popular over the world for designing and architecting applications that can communicate. 

In Java, we use JAX-RS APIs to build RESTful APIs. The JAX-RS is an API specification so we can use either Jersey or RestEasy framework as JAX-RS implementation to build RESTful web services.
