 JFlex is a lexical analyzer generator (also known as scanner generator) for Java(tm), written in Java(tm). It is also a rewrite of the very useful tool JLex which was developed by Elliot Berk at Princeton University.
 As Vern Paxson states for his C/C++ tool flex: They do not share any code though.
-
 JFlex is designed to work together with the LALR parser generator CUP by Scott Hudson, and the Java modification of Berkeley Yacc BYacc/J by Bob Jamison. It can also be used together with other parser generators like ANTLR or as a standalone tool.
