Always Check Type Before Cast

Cover of the book Java by Comparison

"Always Check Type Before Cast" is one of the 70 comparisons in the book Java by Comparison: Chapter 5: Prepare for Things Going Wrong, pages 84–85.

Like every item in the book, it shows a piece of flawed Java code on one page and the improved version on the next, and explains why the improvement is better.
