Day 25: Accessibility

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 25:

Answer (c) is correct. Casting cannot be used to create an int value from an Integer object. Instead, the object's intValue() method should be called, which returns an int of the same value as the object.

Answers (a), (b), and (d) are incorrect.
