Currency and BigDecimal

I’m studying for SCJP – currently tackling a rather dull section on regular expressions. I’ve just noticed that the exam does not cover BigDecimal. I really don’t understand this. BigDecimal is essential for any fixed precision decimal representation and calculation. Put another way: if you’re not aware of BigDecimal, you can’t effectively represent money in your program. Surely more useful than awareness of the \w, \s and \d regex metacharacters, no?
