    /** A Java program that demonstrates console based input and output. */
    public class MyConsoleIO
    {
        // Create a single shared Scanner for keyboard input
        private static Scanner scanner = new Scanner( System.in );

        // Program execution starts here
        public static void main ( String [] args )
