Conventions Used in This Book

Italic is used for:

  • Pathnames, filenames, and program names.

  • New terms where they are defined.

  • Internet addresses, such as domain names and URLs.

Boldface is used for:

  • Particular keys on a computer keyboard.

  • Names of user interface buttons and menus.

Constant Width is used for:

  • Anything that appears literally in a Java program, including keywords, data types, constants, method names, variables, class names, and interface names.

  • Command lines and options that should be typed verbatim on the screen.

  • All Java code listings.

  • HTML documents, tags, and attributes.

  • Method parameters, and general placeholders that indicate that an item is replaced by some actual value in your own program.

  • Variable expressions in command-line options.

  • 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.

  • Highlighting class, method, field, and constructor names in the quick-reference section, which makes it easier to scan the class synopses.

  • Method parameter names and comments in the quick-reference section.
