Day 16: Serializing and Examining Objects

Certification Practice

Each chapter of the book ends with a Certification Practice question that's comparable to what you could expect to be asked on a Java certification test. Here's the answer for chapter 16:

Answer (a) is correct. When you use the new statement to instantiate an object, it will be created as an object of that class. Because Object is a superclass of String (and all other classes), it can be used whenever you're creating an object.

Answers (b), (c), and (d) are incorrect
