javax.json package tutorial

In this tutorial series, I am going to explain about javax.json package. ‘JSR 374’ documents the API contract for JSON processing.

 

javax.json package is part of Java EE and it well documented all the interfaces. You need to provide an implementation library to work with json using javax.json apis (Ex: javax.json artifact from glasshfish provided implementation for javax.json package).

 

I am using following dependencies for this tutorial.

<dependencies>
	<!-- https://mvnrepository.com/artifact/com.google.code.gson/gson -->
	<dependency>
		<groupId>javax.json</groupId>
		<artifactId>javax.json-api</artifactId>
		<version>1.1</version>
	</dependency>


	<dependency>
		<groupId>org.glassfish</groupId>
		<artifactId>javax.json</artifactId>
		<version>1.1.4</version>
	</dependency>

</dependencies>

 

      Create json and print

      Convert json string to JsonObject

      Convert object to json string

      JsonArrayBuilder: build arrays

      Pretty print json

      Build JsonObject from string

      Get an object from json string

      Get list from JsonArray

      Querying using object model api

      Query json using streaming api

      Read json from a file

      Write json string to a file

      Generate json using JsonGenerator

 

You can download the example applications from this link.
