JSON in Java [package org.json]

Maven Central

Click here if you just want the latest release jar file.

Overview

JSON is a light-weight language-independent data interchange format.

The JSON-Java package is a reference implementation that demonstrates how to parse JSON documents into Java objects and how to generate new JSON documents from the Java classes.

Project goals include:

  • Reliable and consistent results
  • Adherence to the JSON specification
  • Easy to build, use, and include in other projects
  • No external dependencies
  • Fast execution and low memory footprint
  • Maintain backward compatibility
  • Designed and tested to use on Java versions 1.6 - 1.11

The files in this package implement JSON encoders and decoders. The package can also convert between JSON and XML, HTTP headers, Cookies, and CDL.

If you would like to contribute to this project

For more information on contributions, please see CONTRIBUTING.md

Bug fixes, code improvements, and unit test coverage changes are welcome! Because this project is currently in the maintenance phase, the kinds of changes that can be accepted are limited. For more information, please read the FAQ.

Build Instructions

The org.json package can be built from the command line, Maven, and Gradle. The unit tests can be executed from Maven, Gradle, or individually in an IDE e.g. Eclipse.

Building from the command line

Build the class files from the package root directory src/main/java

javac org/json/*.java

Create the jar file in the current directory

jar cf json-java.jar org/json/*.class

Compile a program that uses the jar (see example code below)

javac -cp .;json-java.jar Test.java (Windows)
javac -cp .:json-java.jar Test.java (Unix Systems)

Test file contents

import org.json.JSONObject;
public class Test {
public static void main(String args[]){
JSONObject jo = new JSONObject("{ \"abc\" : \"def\" }");
System.out.println(jo.toString());
}
}

Execute the Test file

java -cp .;json-java.jar Test (Windows)
java -cp .:json-java.jar Test (Unix Systems)

Expected output

{"abc":"def"}

Tools to build the package and execute the unit tests

Execute the test suite with Maven:

mvn clean test

Execute the test suite with Gradlew:

gradlew clean build test

JSON in Java [package org.json]
Maven Central
Click here if you just want the latest release jar file.
Overview
JSON is a light-weight language-independent data interchange format.
The JSON-Java package is a reference implementation that demonstrates how to parse JSON documents into Java objects and how to generate new JSON documents from the Java classes.
Project goals include:
  • Reliable and consistent results
  • Adherence to the JSON specification
  • Easy to build, use, and include in other projects
  • No external dependencies
  • Fast execution and low memory footprint
  • Maintain backward compatibility
  • Designed and tested to use on Java versions 1.6 - 1.11
The files in this package implement JSON encoders and decoders. The package can also convert between JSON and XML, HTTP headers, Cookies, and CDL.
If you would like to contribute to this project
For more information on contributions, please see CONTRIBUTING.md
Bug fixes, code improvements, and unit test coverage changes are welcome! Because this project is currently in the maintenance phase, the kinds of changes that can be accepted are limited. For more information, please read the FAQ.
Build Instructions
The org.json package can be built from the command line, Maven, and Gradle. The unit tests can be executed from Maven, Gradle, or individually in an IDE e.g. Eclipse.
Building from the command line
Build the class files from the package root directory src/main/java
javac org/json/*.java

Create the jar file in the current directory
jar cf json-java.jar org/json/*.class

Compile a program that uses the jar (see example code below)
javac -cp .;json-java.jar Test.java (Windows)
javac -cp .:json-java.jar Test.java (Unix Systems)

Test file contents
import org.json.JSONObject;
public class Test {
public static void main(String args[]){
JSONObject jo = new JSONObject("{ \"abc\" : \"def\" }");
System.out.println(jo.toString());
}
}

Execute the Test file
java -cp .;json-java.jar Test (Windows)
java -cp .:json-java.jar Test (Unix Systems)

Expected output
{"abc":"def"}

Tools to build the package and execute the unit tests
Execute the test suite with Maven:
mvn clean test

Execute the test suite with Gradlew:
gradlew clean build test
