Hello,
Java friends!
I think, there is an errata on
Sybex OCP Java 8 Study Guide -> Appendix A Answers To Review Qestions -> Chapter 8: IO -> Question #21 (page 567)
"D is also incorrect because a serialized empty
array is not the same as a null pointer. "
should be
"D is also incorrect because a serialized empty
arrayList is not the same as a null pointer. "
Original question is on page 450. Option D looks like "private java.util.List<Zebra> friends = new java.util.ArrayList<>();"
