Adding New Currency in Java 8
If you are using the java.lang.Currency as part of your entity, most likely you are already regretting it now. Most of the time, a currency is a three letter word, and we don’t need the logic to be bundled in there. Keeping things simple and mapping these currencies as a String or own custom class is the way to go. For people who did use java.lang.Currency, the pain will arrive when a country changed its currency or added a new one.
