Conventions used
There are a number of text conventions used throughout this book.
Code in text: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The corresponding Java main() must be put in a class."
A block of code is set as follows:
procedure main(argv) simple := simple() yyin := open(argv[1]) while i := yylex() do write(yytext, ": ", i) end
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
MethodHeader: PUBLIC STATIC MethodReturnVal
MethodDeclarator {
$$=j0.node("MethodHeader",1070,$3,$4);
j0.calctype($$);
};
Any command-line input or output is written as follows:
$ jflex nnws.l $ javac simple .java yylex.java
Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "Select System info from the Administration panel."
