public class GroupExample

extends Object

An instance of ExchangeFactory contains an exchange rate table and at at least one exchange group. Exchange groups can construct exchange objects which are used to perform currency conversions. When presented with a source/target currency pair the exchange factory searches its list of exchange groups until it finds one that can create an exchange object given the source/target pair and the factory's associated exchange rate table. If no group can create such an object a null value is returned by the factory.

In this example an exchange factory object is created and three exchange groups are added. Several currency exchanges are performed.
