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: "The switch { ... } control flow element is replaced by when { ... }."
A block of code is set as follows:
fun test() {
Bar.NAME
Bar.printName()
}
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
<!-- A bean example with singleton scope -->
<bean id = "..." class = "..." scope = "singleton"/>
<!-- You can remove the scope for the singleton -->
<bean id = "..." class = "..."/>
Any command-line input or output is written as follows:
$ mkdir css
$ cd css
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: "Select System info from the Administration panel."
