Representing Monetary Values in Java [closed]

by

BigDecimal all the way. I’ve heard of some folks creating their own Cash or Money classes which encapsulate a cash value with the currency, but under the skin it’s still a BigDecimal, probably with BigDecimal.ROUND_HALF_EVEN rounding.

Edit: As Don mentions in his answer, there are open sourced projects like timeandmoney, and whilst I applaud them for trying to prevent developers from having to reinvent the wheel, I just don’t have enough confidence in a pre-alpha library to use it in a production environment. Besides, if you dig around under the hood, you’ll see they use BigDecimal too.
