In this book, you will find a number of styles of text 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: "Now we can try to change the code inside the HellovaadinUI class, so the application prints out the name of the system user."
New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "There should be a few Vaadin wizards listed. Choose Vaadin 7 Project and click on the Next button."
