"JSONArray" example in Java

     

In this part of JSON tutorial you will study how to use JSONArray in Java. JSONArray is a sequential and ordered way of collection values.It may consists of Boolean, JSONArray, JSONObject, Number and String or the JSONObject.NULL objects.

To have functionality of JSON in your java program you must have JSON-lib. JSON-lib also requires following "JAR" files:

1. commons-lang.jar 
2. commons-beanutils.jar
3. commons-collections.jar
4. commons-logging.jar
5. ezmorph.jar
6. json-lib-2.2.2-jdk15.jar

JSON-lib is a java library for that transforms beans, collections, maps, java arrays and XML to JSON and then for retransforming them back to beans, collections, maps and others.

In this example we are going to use JSONArray for creating an object of JSONArray and then we will print this array object . For using JSONArray class we have to import package "net.sf.json". To add elements in this object we have used add() method. Here is the full example code of JSONJavaArray.java  as follows:

FirstJSONJava.java


import net.sf.json.JSONArray; public class JSONJavaArray {   public static void main(String args[]){    JSONArray arrayObj=new JSONArray();  arrayObj.add("name :");  arrayObj.add("Amit Kumar");  arrayObj.add("Max.Marks :");  arrayObj.add(new Integer(100));  arrayObj.add("Min.Marks");  arrayObj.add(new Double(40));  arrayObj.add("Scored");  arrayObj.add(new Double(66.67));  System.out.println(arrayObj);   } }

To run this example you have to follow these few steps as follows:

• Download JSON-lib jar and other supporting jars
• Add these jars to your classpath
• create and save JSONJavaArray.java
• Compile it and execute ,You  will get following output:
