how to print nested json-object without escapes and quotation marks

i have a json-object named jsonObject

{
    "action":"Read",
    "infos":[
        {
            "value":0.0350661,
            "key":"first"
        }
    ]
}

i wanna to print the json-object to with the following form

{"action":"Read","infos":[{"value":0.0350661,"key":"first"}]}

if i use jsonObject.toString() method i will get

{"action":"Read","infos":"[{\"value\":0.0350661,\"key\":\"first\"}]"}

if i use StringEscapeUtils.unescapeJava(jsonObject.toString()) method i will get

{"action":"Read","infos":"[{"value":0.0350661,"key":"first"}]"}

if i use jackson mapper with the following code

ObjectMapper mapper = new ObjectMapper();
mapper.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);
String jsonString = mapper.writeValueAsString(getDebugInfo())

i will get jsonString as

{"nameValuePairs":{"action":"Read","infos":[{"value":0.0350661,"key":"first"}]}}

is there any solution to get the desired output json-string?

• JSON Structure

You have that as an object, that is why quotes are not present there.

In your example, an array object is present, at the Json structure.

• Code/Java

While printing at Console, the json body's every Key & Value toString() are referred .

That is why the Double Quotes present, as Strings are getting used!

Here I have tried the below code using GSON library, and it is printing me the correct json as shown above.

public static void main ( String [] args ) {
        
        JsonObject jsonObject = new JsonObject();
        jsonObject.addProperty("action", "Read");
        JsonArray jsonArr = new JsonArray();
        JsonObject jsonObject2 = new JsonObject();
        jsonObject2.addProperty("value", 0.0350661);
        jsonObject2.addProperty("key", "first");
        jsonArr.add(jsonObject2);
        jsonObject.add("infos", jsonArr);
        
        
		String jsonString = jsonObject.toString();
		Gson gson = new GsonBuilder().setPrettyPrinting().create();
		JsonElement json = gson.fromJson(jsonString,JsonElement.class);
		String jsonInString = gson.toJson(json);
		System.out.println(jsonInString);
}

OUTPUT:

{
  "action": "Read",
  "infos": [
    {
      "value": 0.0350661,
      "key": "first"
    }
  ]
}

Even if I am forming the jsonObject using org.json, and simple printing it using System.out.println(jsonObject.toString()); on console, m getting the result like this.

{"action":"Read","infos":[{"value":0.0350661,"key":"first"}]}

So here, not sure how you have formed your jsonObject.
