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: "Th last member variable is a LayoutInflater instance, which will be used to inflate each of the instances of pager_item.xml."

A block of code is set as follows:

@Override
public int getCount() {
   return images.length;
}

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

import androidx.appcompat.app.AppCompatActivity;
import androidx.viewpager.widget.PagerAdapter;
import androidx.viewpager.widget.ViewPager;

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

$ mkdir css
$ cd css

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
