Potential errata in Boyarsky and Selikoff Java SE 8 Programmer I Study Guide Exam

[Vitaliy Ovcharenko]

Of course it is not too important but I think that one more potential errata should be added on the book web-page. It concerns question number 13 of assessment test. Literally the sentence in the book says "Since luck is not less than 10, the second expression,
--luck, will be evaluated, and since the pre-increment operator was used, the value returned will be 9, which is less than 10". But actually as it follows from the text pre-decrement operator is used for variable luck.

The next sentence "So the first if-then statement will be visited and Bear will be output." also looks little bit confusing because java statement "if" does not have "then" as some another programming languages.

Confirmed and added to the errata page.

That's not an errata. People commonly refer to an if statement as an if then statement even though "then" doesn't appear in the syntax of Java. It's understandable both ways.
