FxConvertible<Money>
,Serializable
,Comparable<Money>
public class Money extends Object implements FxConvertible<Money>, Comparable<Money>, Serializable
An amount of a currency, rounded to match the currency specifications.This class is similar to
CurrencyAmount
, but only exposes the rounded amounts. The rounding is done usingBigDecimal
, as BigDecimal.ROUND_HALF_UP. Given this operation, it should be assumed that the numbers are an approximation, and not an exact figure.This class is immutable and thread-safe.
