In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "NetBeans uses the JAVA_HOME environment variable to populate the JDK's directory location."

A block of code is set as follows:

<package com.ensode.flowscope.namedbeans;

import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.faces.flow.FlowScoped;
import javax.inject.Named;

@Named
@FlowScoped("registration")
public class RegistrationBean {
...

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

package com.ensode.flowscope.namedbeans;

import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.faces.flow.FlowScoped;
import javax.inject.Named;

@Named
@FlowScoped("registration")
public class RegistrationBean {
...

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

chmod +x filename.sh

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: " To download NetBeans, we need to click on the Download button."
