Conventions

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: "The action takes place within the overridden processEntity() method responsible for the logic"

A block of code is set as follows:

public class DesktopResolver implements PlatformResolver {
   @Override
   public void rateGame() {
      System.out.println("Desktop");
      Gdx.net.openURI("https://facebook.com");
   }
}

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

public String getCurrentLanguage() {
return currentLanguage;
}
public void setCurrentLanguage(String name) {
if(languages.containsKey(name.toLowerCase()))
currentLanguage = name;
}

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

tar –xzvf android-sdk.r22.2.1-linux.tgz

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: "Install the Gradle IDE entry and restart Eclipse for the last time."

Note

Warnings or important notes appear in a box like this.
