     * We can use varargs when you don't know how many of a particular type of
     * argument will be passed to the method.
     * 
     * It's a shortcut to creating an array manually.
     * 
     * To use varargs, you follow the type of the last parameter by an ellipsis
     * (three dots, ...), then a space, and the parameter name.The method can
     * then be called with any number of that parameter, including none.
