Welcome to the Core Java Bug List

How to Tell which Printing You Have

On the bottom of the copyright page (facing the first page of the table of contents), look for a line such as
First printing, December 2012

In the errata below, we indicate the printing in which the error has been fixed inside square brackets such as [4].

For example, suppose you have the fourth printing. Then you can ignore all reports that are prefixed with [2], [3] or [4]. But you would want to pay attention to all reports that are prefixed with [5] or higher or that have no bracketed prefix at all.

9th Edition Volume 1 (Java SE 7)

Page 51
Change "For example, the mathematical symbol for the set of integers ℤ has code point U+1D56B and is encoded by the two code units U+D835 and U+DD6B." to "For example, the mathematical symbol for the set of octonions 𝕆 (http://math.ucr.edu/home/baez/octonions) has code point U+1D546 and is encoded by the two code units U+D835 and U+DD46.”

(Why the change? When I first wrote that section, way back when in 2004, I mistook 𝕫 (U+1D56B), which is in Mathematical Letterlike Symbols, for an uppercase ℤ, which is actually U+2124 in Letterlike Symbols, as are the other more common sets ℕ ℚ ℝ ℂ and even ℍ. Apparently, so few readers care about supplementary characters that it took eight years for the error to be noticed.)

If the characters in the preceding paragraphs show up as gibberish, make sure your browser displays UTF-8.

Change the second 3.6.5 to 3.6.6, and increment the section numbers on pages 69, 72, 74 and the references on pages 66 and 70.
Page 69
Change 
ℤ is the set of integers

to

𝕆 is the set of octonions

Change “The character ℤ” to “The character 𝕆 (U+1D546)”
