You can try the following code:
JSONObject user1 = new JSONObject();
try {
user1.put("user_id", "7");
user1.put("group_id", "askskdjejs139d");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONObject user2 = new JSONObject();
try {
user2.put("user_id", "16");
user2.put("group_id", "askskdjejs139d");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONArray jsonArray = new JSONArray();
jsonArray.put(user1);
jsonArray.put(user2);
JSONObject userObj = new JSONObject();
userObj.put("Users", jsonArray);
String jsonStr = userObj.toString();
System.out.println("jsonString: "+jsonStr);

You can do this using org.json Library.
Given below are some examples:
// Creating a json object
JSONObject jsonObj = new JSONObject();
// Adding elements to json object
jsonObj.put("key", "value"); // the value can also be a json object or a json array
// Creating a json object from an existing json string
JSONObject jsonObj = new JSONObject("Your json string");
// Creating a json array
JsonArray jsonArray = new JsonArray();
// Adding a json object to json object to json Array
jsonArray.add(jsonObj);
// Adding json array as an element of json object
jsonObject.put("key", "<jsonArray>");
You can call toString() method of JsonObject or JsonArray to get the String representation of the json object/array.
