Convert JsonObject into String using Java

Question

I am getting some values from mongodb via Java Spring API. For sofTagList as in image below, I am getting List<JsonObject> for that. I am trying to access the value field inside tagName . When I itereate the list, I am getting null values each and every time. I tried googling and convert that JsonObject to String. But that doesn't help me to solve my issue. I am using com.google.gson.JsonObject package. Here is the screen shot of my mongodb which I am trying to access.

Edit 1: Added code Snippet.

if(null!=person.getSofTagList()){
                    List<JsonObject> jsonObj = person.getSofTagList();
                    System.out.println("Size is   ========>>  "+ jsonObj.size());
                    for (JsonObject jsonObject : jsonObj) {
                        System.out.println("GetTag Name         "+jsonObject.getAsJsonObject("tagName"));                       
                    }
                }

When printing size I am getting 30 as shown in image. It loops for 30 times in for loop but all time null is the output. Hope my question is clear. Thanks in advance.

Answer 1

Update the code inside the for loop as below :

 JSONArray msg = (JSONArray) jsonObject.get("tagName");
            Iterator<String> iterator = msg.iterator();
            while (iterator.hasNext()) {
                System.out.println(iterator.next());
            }
