Encoding JSON In Java With Simple Example
In this article, I am going to tell you how to encode JSON objects using Java programming language with simple example code. I hope you will enjoy this tutorial.
At first, you need to prepare the environment for this tutorial. Before you start writing code and encoding using Java, you need to install a JSON module. In this tutorial, I am going to use JSON.simple. Now need to be added the location of json-simple-1.1.1.jar file to the environment variable CLASSPATH.
Java code for Encoding JSON
Following is a simple example of encoding a JSON object using Java JSONObject. JSONObject is a subclass of java.util.HashMap.
Below is the given Java code:
import org.json.simple.JSONObject; class JsonEncodeExample { public static void main(String[] args){ JSONObject obj = new JSONObject(); obj.put("name", "Jone"); obj.put("phone_number", new Integer(4578356945)); obj.put("balance", new Double(155.62)); obj.put("is_present", new Boolean(true)); System.out.print(obj); } }
After compiling and executing the above java program it will return the output result that is given below:
{"balance": 155.62, "phone_number":5269873622, "is_present":true, "name":"Jone"}
I am going to give you another example which will show a JSON object streaming using Java JSONObject. below is the Java code:
import org.json.simple.JSONObject; class ExampleJsonDemo { public static void main(String[] args){ JSONObject obj = new JSONObject(); obj.put("name","Jone"); obj.put("phone_number",new Integer(5269873622)); obj.put("balance",new Double(155.62)); obj.put("is_present",new Boolean(true)); StringWriter out = new StringWriter(); obj.writeJSONString(out); String jsonText = out.toString(); System.out.print(jsonText); } }
And the output result of above code after compiling and executing will be:
{"balance": , "phone_number":5269873622, "is_present":true, "name":"Jone"}
