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: "The complete code for this mini-app can be found on the GitHub repo in the Chapter 4/Method overloading folder."

A block of code is set as follows:

private void setCoordinates(int x, int y){
	// code to set coordinates goes here
}

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

int addAToB(int a, int b){
	int answer = a + b;
	return answer;
}

Bold: Indicates a new term, an important word, or words that you see onscreen. 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."
