To get the most out of this book
You should have basic knowledge of Java and know what the JVM is. It is also assumed that you are comfortable working with the command line. A few command-line examples we use in this book are based on OS X but could be easily adapted for Windows or Linux.
If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
