Conventions Used in This Book

Italic is used for:

• Pathnames, filenames, and program names

• Internet addresses, such as domain names and URLs

Typewriter Font is used for:

• Anything that might appear in a Java program, including keywords, method names, variables names, class names, and interface names

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

• Tags that might appear in an HTML document

To sort out the potential for confusion between different versions, I use the following dingbats throughout the book:

Identifies a method, variable, or constant that is new in Java 1.1.

Identifies a method from Java 1.0 that has been deprecated. Deprecated methods are available for compatibility but may disappear in a future release. These methods are tagged with the @deprecated flag, which causes the Java 1.1 compiler to display a warning message if you use them.
