Conventions Used in This Book (Java in a Nutshell)

0.6. Conventions Used in This Book

We use the following formatting conventions in this book:

Italic: Used for emphasis and to signify the first use of a term. Italic is also used for commands, email addresses, web sites, FTP sites, file and directory names, and newsgroups.
Bold: Occasionally used to refer to particular keys on a computer keyboard or to portions of a user interface, such as the Back button or the Options menu.
Letter Gothic: Used in all Java code and generally for anything that you would type literally when programming, including keywords, data types, constants, method names, variables, class names, and interface names.
Letter Gothic Oblique: Used for the names of function arguments and generally as a placeholder to indicate an item that should be replaced with an actual value in your program.
Franklin Gothic Book Condensed: Used for the Java class synopses in the quick-reference section. This very narrow font allows us to fit a lot of information on the page without a lot of distracting line breaks. This font is also used for code entities in the descriptions in the quick-reference section.
Franklin Gothic Demi Condensed: Used for highlighting class, method, field, property, and constructor names in the quick-reference section, which makes it easier to scan the class synopses.
Franklin Gothic Book Compressed Italic: Used for method parameter names and comments in the quick-reference section.
