Java Object Oriented Class design based on type

I have a requirement where some data is coming from client in json form where some of the fields will be null based on type.

Sample of data is

class Data{
    String type;
    Property1 prop1;
    Property2 prop2;
    Property3 prop3;
    Property4 prop4;
    List<Property5> prop5;
}


class Property5{
    String a;
    String b;
    String c;
}

Here Data object is coming from client and based on type=type1 (prop2 will be null) for type=type2(prop1 will be null) for type=type3 (prop4 will be null)

I have to save this data in db based on type value data will be saved after different transformations.

How to design this in OOPS.Shall I use various switch,case or use subclasses based on type to handle DATA object.
