Joda Convert - Java API to convert Objects to and from Strings
Joda-Convert provides a small set of classes to aid conversion between Objects and Strings. It is not intended to tackle the wider problem of Object to Object transformation. Joda-Convert supports two mechanisms of extending the list of supported conversions. The first is to write your own converter implementing an interface. The second is to use annotations.
