The listing 1.2 specifies only the font-style, but in the text immediately preceding it, and then in the second one after it, the text color is discussed. It is likely a mistake.

Also the code provided in github does not looks like the Figure 2.1

And the author does not explain the origin of the class outline.

Thanks for the heads up. These have been fixed (not sure when those changes will make it to the MEAP, though)
