Difference between pojo vs model class in java

Question

I am working on android app in which I am using gson library for serialization & de(serialization).

Below is the java class I am using for serialization & de(serialization). I am not sure is this model or pojo class.

public class Result {
    private String userId;
    private String sessionId;
}

Can anyone share what it is main difference between model & pojo class.

Thanks in advance

Answer 1

This would be a model class.

Model classes often represent a composition of properties from more than one POJO/POCO class for a specific use.

In your case, you have both a User and Session class. Your Result class is a composite of properties from your Session and User classes.
