The font conventions used in this book are quite simple.

Unix pathnames, filenames, and program names
Internet addresses, such as domain names and URLs
New terms where they are defined
- Boldface is used for:
Names of GUI buttons and menus
-
Constant width
is used for: Anything that might appear in a Java program, including method names, variable names, and class names
Command lines and options that should be typed verbatim on the screen
Tags that might appear in an HTML document
-
Constant width bold
is used for: In code examples, text that is typed by the user
In the main body of text, we always use a pair of empty parentheses after a method name to distinguish methods from variables and other creatures.
In the Java source listings, we follow the coding conventions most
frequently used in the Java community. Class names begin with capital
letters; variable and method names begin with lowercase. All the
letters in the names of constants are capitalized. We don’t use
underscores to separate words in a long name; following common
practice, we capitalize individual words (after the first) and run
the words together. For example: thisIsAVariable
,
thisIsAMethod( )
, ThisIsAClass
,
and THISISACONSTANT
