如何在JsonArray（com.google.gson）中将Empty字符串转换为null

Question

My JSON Object has some empty values ("") So While converting it throws error.

Here's my JSON

{
    "Animals": [
        {
            "id": 6140,
            "Name": ""
        },
        {
            "id": 6144,
            "Name": "Lion"
        }
    ]
}

My Code:

JsonParser parser=new JsonParser();
JsonArray myarray=parser.parse(json).getAsJsonArray();

I'm getting the error as

com.google.gson.stream.malformedjsonexception

How do I convert the empty string values into null while parsing the JSON object as a JSONArray?

I want the final result to be

[{id=6140, Name=null},{id=6144, Name="Lion"}]

This is happening because the json you provided is not a json array, it is a json Object. you should do

    JsonParser json = new JsonParser();
    JsonObject myJsonObject = json.parse(json).getAsJsonObject();
    JsonArray jsonArray = myJsonObject.getAsJsonArray("Animals");
