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, path names, dummy URLs, user input, and Twitter handles are shown as follows: "The Source Packages file is where we'll be writing our code."
A block of code is set as follows:
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
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 class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
Any command-line input or output is written as follows:
java -jar WritingToFiles.jar
