[NSWI080] Task 2 - Java - Accessing (non existing) optional field

[Petr Tuma]

Hi,

you should first check whether the field is set with `isSet`. Calling the getter without first checking for presence returns `0` for integers, `0.0` for floats, `null` for strings etc.

E.g. if ItemA doesn't have fieldZ defined; will it throw some exception or will it just return default value of the type of field?
