I am reading papers of john r. koza , stanford professor who writes genetic algorithm programs for design of new lenses which work on KOJAC 1.0 Ray Tracing Program, a JAVA program.
I downloaded the code written in java , there were little java files in a row.
How can I make work such a code in xp ?
This JAVA code is 60 kbyte size , very small in size.
I am totally strange to programmer guides , i m lost in them.

Thank you ,
