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. Also, note that we differentiate between static and nonstatic methods when we refer to them. Unlike some books, we never write Foo.bar( ) to mean the bar( ) method of Foo unless bar( ) is actually static.
