With the imports <code>org.json.JSONArray</code> and <code>org.json.JSONObject</code>

<pre><code>JSONObject object = new JSONObject();
object.put("name", "sample");
JSONArray array = new JSONArray();

JSONObject arrayElementOne = new JSONObject();
arrayElementOne.put("setId", 1);
JSONArray arrayElementOneArray = new JSONArray();

JSONObject arrayElementOneArrayElementOne = new JSONObject();
arrayElementOneArrayElementOne.put("name", "ABC");
arrayElementOneArrayElementOne.put("type", "STRING");

JSONObject arrayElementOneArrayElementTwo = new JSONObject();
arrayElementOneArrayElementTwo.put("name", "XYZ");
arrayElementOneArrayElementTwo.put("type", "STRING");

arrayElementOneArray.put(arrayElementOneArrayElementOne);
arrayElementOneArray.put(arrayElementOneArrayElementTwo);

arrayElementOne.put("setDef", arrayElementOneArray);
array.put(arrayElementOne);
object.put("def", array);
</code></pre>

I did not include first array's second element for clarity. Hope you got the point though.

EDIT:

The previous answer was assuming you were using <code>org.json.JSONObject</code> and <code>org.json.JSONArray</code>.

For <code>net.sf.json.JSONObject</code> and <code>net.sf.json.JSONArray</code> :

<pre><code>JSONObject object = new JSONObject();
object.element("name", "sample");
JSONArray array = new JSONArray();

JSONObject arrayElementOne = new JSONObject();
arrayElementOne.element("setId", 1);
JSONArray arrayElementOneArray = new JSONArray();

JSONObject arrayElementOneArrayElementOne = new JSONObject();
arrayElementOneArrayElementOne.element("name", "ABC");
arrayElementOneArrayElementOne.element("type", "STRING");

JSONObject arrayElementOneArrayElementTwo = new JSONObject();
arrayElementOneArrayElementTwo.element("name", "XYZ");
arrayElementOneArrayElementTwo.element("type", "STRING");

arrayElementOneArray.add(arrayElementOneArrayElementOne);
arrayElementOneArray.add(arrayElementOneArrayElementTwo);

arrayElementOne.element("setDef", arrayElementOneArray);
object.element("def", array);
</code></pre>

Basically it's the same, replacing the method 'put' for 'element' in JSONObject, and 'put' for 'add' in JSONArray.

Here is one crude example. You should be able to refine. (You may be interested in this Java "tutorial" <a href="http://docs.oracle.com/javaee/7/tutorial/doc/jsonp.htm#GLRBB" rel="nofollow">http://docs.oracle.com/javaee/7/tutorial/doc/jsonp.htm#GLRBB</a>

public class JSONExample {

 } catch (IOException e) {

 e.printStackTrace();
 }
 JsonGenerator gen = Json.createGenerator(writer);

 gen.writeStartObject().write("name", "sample")

I want to build a JSON Object similar to following the structure in java using JSONObject and JSONArray.

I have gone through various posts in stack overflow, which suggests using methods like push, put etc which I am unable to identify for JSONArray. Please help. 

<pre><code>{
 "name": "sample",
 "def": [
 {
 "setId": 1,
 "setDef": [
 {
 "name": "ABC",
 "type": "STRING"
 },
 {
 "name": "XYZ",
 "type": "STRING"
 }
 ]
 },
 {
 "setId": 2,
 "setDef": [
 {
 "name": "abc",
 "type": "STRING"
 },
 {
 "name": "xyz",
 "type": "STRING"
 }
 ]
 }
 ]
}
</code></pre>

Creating nested JSON object for the following structure in Java using JSONObject?

我想使用JSONObject和JSONArray构建一个类似于java中的结构的JSON对象。我已经看过堆栈溢出中的各种帖子，其中建议使用推送、put等我无法识别的JSONArray方法。请帮帮忙。{    "name": "sample",    "def": [        {            "setId...
