There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Flux<T> is a Publisher<T> with basic flow operations and supports 0..n elements."

A block of code is set as follows:

public abstract class Flux<T>
    extends Object
    implements Publisher<T>

Any command-line input or output is written as follows:

curl http://localhost:8080/api/movie -v -u admin:password

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Enter the username as admin and password as password and click on Sign in."
