Please do not double post. Now I don't know what Flex is and don't see the connection with Java. Try the program's help file or google for flex tutorials.
Hahaha, this is what I found for flex when I searched wikipedia under the "computer" sections:
* FLEX (operating system), a single-tasking operating system was developed by Technical Systems Consultants for the Motorola 6800 and 6809 MPUs beginning in the 1970s
* FLEX (protocol), a communication protocol developed by Motorola and used in many pagers
* Flex lexical analyser, a free software alternative to Lex
* Flex machine
* Adobe Flex, a technology for developing rich internet applications initially released by Macromedia in March of 2004
* FLEX, a family of automatic test equipment produced by Teradyne
Adobe Flex or Flex lexical analyser is the closest two things I think it could be... why he's posted about it here I don't know...
