How to add values ​​to json array?

Question

Java

How can i write new data to json array? I have a json file, it has an array of Workers, which consists of the name, age, pay, post keys and their values. How can I write 4 more of the same keys to this array? I am using the Simple Json library

json

{
  "Workers": [
  {
    "name": "Имя1",
    "post": "Должнось1",
    "age": 24,
    "pay": 20000
  },
  {
    "name": "Имя2",
    "post": "Должнось2",
    "age": 25,
    "pay": 16000
  }
    //Добавить вот так
    // {
    //    "name": "Имя3"
    //    "post": "Должность3"
    //    "age": "27"
    //    "pay": "15000"
    // },
]
}

The code I'm reading the file with

FileReader reader = new FileReader(filePath);

 JSONParser jsonParser = new JSONParser();
 JSONObject jsonObject = (JSONObject) jsonParser.parse(reader);

 JSONArray lang= (JSONArray) jsonObject.get("Workers");
 Iterator i = lang.iterator();
 while (i.hasNext()) {
    JSONObject innerObj = (JSONObject) i.next();
    System.out.println("ФИО: " + innerObj.get("name") + "\n"
            + "Должность: " + innerObj.get("post") + "\n"
            + "Возраст: " + innerObj.get("age") + "\n"
            + "Зарплата: " + innerObj.get("pay") + "\n");
