JSON.simple - Primitive, Object, Array



Using JSONArray object, we can create a JSON which comprises of primitives, object and array.

Following example illustrates the above concept.

Example

import java.io.IOException; import org.json.simple.JSONArray; import org.json.simple.JSONObject; class JsonDemo { public static void main(String[] args) throws IOException { JSONArray list1 = new JSONArray(); list1.add("foo"); list1.add(new Integer(100)); JSONArray list2 = new JSONArray(); list2.add(new Double(1000.21)); list2.add(new Boolean(true)); list2.add(null); JSONObject obj = new JSONObject(); obj.put("name", "foo"); obj.put("num", new Integer(100)); obj.put("balance", new Double(1000.21)); obj.put("is_vip", new Boolean(true)); obj.put("list1", list1); obj.put("list2", list2); System.out.println(obj); } }

Output

{"list1":["foo",100],"balance":1000.21,"is_vip":true,"num":100,"list2":[1000.21,true,null],"name":"foo"}
