Java is a general-purpose language - it can be used for just about anything you can think of, certainly in applications programming.
JOONE is a Java API for implementing Neural Networks (or Artifical Neural Networks, the terms really mean the same thing when it comes to software implementations). It includes all jar files you need to get started using it.

See if you can read an extract on Amazon or borrow a copy. If I remember correctly the examples are in such a form that they can easily be converted to Java. Round here, the AI people seem to use LISP, and the Games AI chaps use C, and if it can be written in C it can probably be written in Java.
sounds good to take it as a learning project. Can I get some suggestions from experts here about where all we can implement this. My aim is to make something which can be used by a number of people.... means in the direction of Open source..... not any libraries... but some software which can be used...
