3 ways to parse JSON String to Object in Java [Jackson, Gson, and json-simple Example]

One of the common task in Java web application, particularly the ones which deals with RESTful web services are parsing JSON messages. Many times you need to parse JSON to create a Java object like parsing a JSON message to create a POJO,  for example, an Order or a Book. Representing JSON in Java is easy, it's like a String value but unfortunately, JDK doesn't provide any standard API to parse JSON in Java. There were talks to add JSON parsing API in JDK 9 but that didn't materialize, but you don't need to worry. There are many good open-source JSON parsing libraries you can use to parse any kind of JSON in your Java program.
