Conventions used
There are a number of text conventions used throughout this book.
Code in text: 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: “When an exception is thrown inside a try block, it redirects control flow to the first catch clause.”
A block of code is set as follows:
void someMethod(String s){
try {
method(s);
} catch (NullPointerException ex){
//do something
} catch (Exception ex){
//do something else
}
}
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 TheParentClass {
private int prop;
public TheParentClass(int prop){
this.prop = prop;
}
// methods follow
}
Any command-line input or output is written as follows:
--module-path /path/JavaFX/lib \ :-add-modules=javafx.controls,javafx.fxml
Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Select a value for Project SDK (java version 12, if you have installed JDK 12 already) and click Next”.
