Conventions used in the book

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: "We will create a message Producer class."

A block of code is set as follows:

class Producer {
  @Inject
  private lateinit var initialContext: InitialContext
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

class Producer {
  @Inject
  private lateinit var initialContext: InitialContext
}

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

> kotlinc -script 14c_SecondaryConstructor.kts

Bold: Indicates a new term, an important word, or words that you see on screen. For example: "The Java Messaging System (JMS) is the standard API for messaging systems."
