When an object is serialized, if it has reference to other objects, thos objects must be serializable. [TRUE]


Source: K&B Bonus exam

I don't this as true statement.

Please see the code below, how I take this statement as false:



We can easily serialize an object of Dog, no issue of Animal class not serializable, until we are creating instance of Animal in the Dog class.

This issue was very latest discussed but I see this statement marked true in K&B bonus exam.

Please suggest.

I guess it is true becuase the words in bold mean that the reference pointing to other objects....

In the case of the given code example, the reference is pointing to null...


What do you say?

No. The reference variable has the value null. It is not referring (or pointing) to anything at all.

It has a reference to other object and it is not serializable.
