使用 java 从 JSON 获取动态子数组

Question

I am trying to read json using java which contains data of a menu created by Jquery Plugin.

    [
  {
    "text": "Home",
    "href": "http://home.com",
    "icon": "fas fa-home",
    "target": "_top",
    "title": "My Home"
  },
  {
    "text": "Option1",
    "href": "",
    "icon": "fas fa-map-marker",
    "target": "_self",
    "title": "",
    "children": [
      {
        "text": "Option1.1",
        "href": "",
        "icon": "fas fa-search",
        "target": "_self",
        "title": "",
        "children": [
          {
            "text": "Option1.1.1",
            "href": "",
            "icon": "fas fa-plug",
            "target": "_self",
            "title": "",
            "children": [
              {
                "text": "Option1.1.1.1",
                "href": "",
                "icon": "fas fa-filter",
                "target": "_self",
                "title": ""
              }
            ]
          }
        ]
      },
      {
        "text": "Option1.2",
        "icon": "fab fa-amazon-pay",
        "href": "",
        "target": "_self",
        "title": "",
        "children": [
          {
            "text": "Option1.2.1",
            "icon": "empty",
            "href": "",
            "target": "_self",
            "title": ""
          }
        ]
      }
    ]
  },
  {
    "text": "Option2",
    "icon": "fab fa-adversal",
    "href": "",
    "target": "_self",
    "title": ""
  }
]

Visual representation of this json will be like

Children array is created dynamically. It can be in every object. Is there a way to read the children array which is inside of other children arrays?

I'm using json-simple to read the json file and my current code is:

 JSONParser parser = new JSONParser();
        Object obj = parser.parse(new FileReader("C:\\Users\\ryuuk\\Desktop\\data.json"));
        JSONArray jsonArray = (JSONArray) obj;
        for (Iterator it = jsonArray.iterator(); it.hasNext();) {
            JSONObject object = (JSONObject) it.next();
            System.out.println(" <li><a href=\"#\">" + object.get("text") + "</a>");
            if (object.containsKey("children")) {
                System.out.println("<ul>");
                JSONArray achil = (JSONArray) object.get("children");
                for (int i = 0; i < achil.size(); i++) {
                    JSONObject objectx = (JSONObject) achil.get(i);
                    System.out.println(" <li><a href=\"#\">" + objectx.get("text") + "</a>");
                }
                System.out.println("</ul>");
            }
        }

Which will output this:

 <li><a href="#">Home</a>
 <li><a href="#">Option1</a>
<ul>
 <li><a href="#">Option1.1</a>
 <li><a href="#">Option1.2</a>
</ul>
 <li><a href="#">Option2</a>

How can I read those children arrays in Option1.1.1 ?
