// NOTE: what happened to variable called exception? Nothing useful...but,
// you could have used exception to print out info, like the call stack trace.
// the variable exception is a ref to an object of class ArithmeticException
// which inherits methods, like printStackTrace(), from Throwable.
// So, why bother? Useful for debugging, since catch won't automatically
// report the exception.
