Yes, the following method is there exactly for that. You need an EPSG database 
however, either the embedded JavaDB or a database on PostgreSQL, at your choice.

http://www.geotoolkit.org/apidocs/org/geotoolkit/referencing/CRS.html#lookupIdentifier(org.opengis.referencing.IdentifiedObject,%20boolean)

Please let me know if you have any issue.
