Conventions used

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: "An ApplicationStartedEvent will be sent right after the application context is refreshed but before any command-line runners run. "

A block of code is set as follows:

public class Address {
    private String number;
    private String street;
    private String city;
    private String country;
    private String zipCode;
    // Getters, Setters, Equals, Hashcode
}

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

$ jconsole

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 File | Open from the menu bar."
