Parse JSON Data using POJO, Where key name is numeric

I'm trying to parse a special JSON data using Wrapper class, special means a JSON which have numeric keys like below :

{
"date":"2018-11-01",
"hours":"01-Nov 08:00",
"1011":"837.7500",
"1022":"99.92596979567664",
"1010":"3.198083",
"1021":"5",
"1019":"1171.000",
"1018":"3.578371",
"1017":"30.46989",
"1016":"0.0001931423",
"1015":"6749",
"1014":"0.161805",
"1013":"0.001678397",
"1012":"1.406077"
}

I know how to parse JSON data using POJO, But in this case java is not accepting the numeric as Keys.

Wrapper/POJO Class

I don't want to go with JSON object based parsing. Is Anyone have any idea about it?

Solution

  • The Gson library has SerializedName functionality in which it parses the corresponding value of the key defined in SerializeName's parameter. Things will be tougher if your key is a pure integer since Java disallows it as variable name, in this case SerializeName will save you from that headache and it makes your code way more maintainable.

    Example usage : 

    @SerializedName("1011") double lat;
@SerializedName("1022") double lng;
