JFlex is a lexical analyzer generator for Java written in Java. It is also a rewrite of the very useful tool JLex which was developed by Elliot Berk at Princeton University. As Vern Paxon states for his C/C++ tool flex: They do not share any code though. WWW: http://www.jflex.de/ I've done some clean up to the submitted version of the port.
