Errata

There is a typo in the book by link:
https://www.safaribooksonline.com/library/view/java-pocket-guide/9781491938683/ch04.html

Class Song {
String title;
Artist artist;
float length;
Year year;
void setData() {...}
}

Word "class" should not starts with capital letter here.

Note from the Author or Editor:
I agree. 'Class' should read 'class'.

Thank you for the errata submission.

The optional static modifier of the requires keyword is not listed. This feature is not documented in the chapter either.

Note from the Author or Editor:
On page 224, please change:
[requires [transitive] <module name>]
should read
[requires [transitive] [static] <module name>]

On page 225, please add this sentence to the end of the Declaring Dependencies section.

The optional static keyword is for compile time dependencies.

The syntax for the opens and exports statements allow multiple comma separated qualified module names and the provides statement allows multiple types to be listed. The text strongly suggest that only one package/type is allowed.

Note from the Author or Editor:
On page 224, please change this statement:

"All public types in a package may be exported by adding an export statement to a module definition:"

to the following:

"All public types in a package may be exported by adding one or more export statements to the module definition:"
