Maintenance Lead Werner Keil will present JSR 354 (Money and Currency). They will discuss the API from a developer as well as user perspective and share details on the design decisions behind the JSR. Monetary values are a key feature of many applications, yet the JDK provides little or no support. The existing java.util.Currency class is strictly a structure used for representing current ISO-4217 currencies, but not associated values or custom currencies. The JDK also provides no support for monetary arithmetic or currency conversion, nor for a standard value type to represent a monetary amount. The session will demonstrate how the JSR models monetary capabilities, monetary amounts, currencies, rounding, financial arithmetics as well as formatting and currency conversion in a platform independent and flexible manner. The first part of the talk will focus on key concepts, improvements like Java 9/Jigsaw modularity and planned new features for a future release followed by a live coding session demonstrating the Money JSR in action.
