JSR 354 provides an API for representing, transporting, and performing comprehensive calculations with Money and Currency. This module implements JSR 354. This module provides the test code that is compatible with both the Java 7 and the Java 8 based API. The targeted API must be provided as well as the implementation under test to execute this TCK.
The newest version!
