Sybex 816, Appendix B, page 688 errata

[Matus Iglarcik]

In answer to question 22 (Chapter 9: NIO.2) there is:

The APPEND option creates the file if it does not exist...

It refers to this code:

var w = Files.newBufferedWriter(x, StandardOpenOption.APPEND);

If the file does not exist, function newBufferedWriter will create it if:

no option at all is present (in this case method works as if the CREATE, TRUNCATE_EXISTING, and WRITE options are present; link to java docs)

option for creating is present (CREATE/CREATE_NEW)

Since StandardOpenOption.APPEND is already present, option for creating file must by written explicitly. Otherwise NoSuchFileException is thrown when file does not exist.
Therefore option B is not correct and option C is correct.

[Campbell Ritchie]

Didn't find that in the errata. You are correct; I also tried such code on JShell and failed to create the file.

[Jeanne Boyarsky]

Agreed. Added to errata
