Conventions

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, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The SSLSocketFactory class' getDefault returns an SSLSocketFactory instance whose createSocket creates a socket that is connected to the secure echo server."

A block of code is set as follows:

public class ThreadedEchoServer implements Runnable {
    private static Socket clientSocket;

    public ThreadedEchoServer(Socket clientSocket) {
        this.clientSocket = clientSocket;
    }
    ...
}
