Conventions

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: " we can use this.gender == FEMALE; instead of this.gender.equals("Female");."

A block of code is set as follows:

Boolean t1 = new Boolean (true);
System.out.println(t1=!Boolean.TRUE);
System.out.println(t1.==(Boolean.TRUE));
produces the output: False OR True

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: " After logging in, the user can navigate to Test Centre "
