What is the POJO equivalent for this nested json?

Question

There is a json response of a webservice :

{
  "data": {
            "token": "e3a5776e-bf55-4bf8-a6e3-008c849089da"
          },
  "error": null
}

I want to make a POJO for it ; what should be its structure ?

Answer 1

Assuming error is an Object, following is the POJO.

public class Data{
    public String token;
}

public class MainObj{
    public Data data;
    public Object error;
}
