Java POJO Modelling

Question

I want a POJO to contain a Status field (only two possible values SUCCESS, FAILED) and depending on this status, the second field needs to be

1. either a POJO object( if Status is SUCCESS)
2. or just String error message(if Status is FAILED)

What should be the data type of the second field in POJO?

public class MyBean {
    private Status status,
    private ??? body
}

Answer 1

JSON is also a String, So you can define it as String itself.

When exchanging data between a browser and a server, the data is mostly text and represented in JSON format.

public class MyBean {
    private Status status;
    private String body;
}
