Netica-J: Java version of the Netica API

Netica-J offers the complete Netica API in Java. If you are a Java developer this is exactly what you have been wanting, a very clean and natural object-oriented way to access all of Netica's power.

The Netica Java-API is one member of the family of Netica APIs, including ones for C, C++, and Visual Basic.


Java-API Features

This list outlines features specific to the Java-API. For the features shared by all the Netica APIs, please see the Netica API page.

  • Well written and easy to understand user's manual, and a comprehensive, detailed, and well cross-indexed function reference (javadocs).
  • A clean object-oriented design
  • Sample applications to get you started
  • Source code for dozens of powerful utility functions in "Extra" classes: NetEx, NodeEx, and NodeListEx
  • High performance, relying on the same ultra-reliable industrial-strength computation engine in Netica's C-API (hundred's of fielded applications over the past five years)
  • Natural and easy to use for any Java developer. Designed by Java developers for Java developers. For instance:
    • Uses Java's exception handling mechanism exactly as you'd expect, greatly simplifying your code
    • Supports event listening by any Java object for events such as the creation, deletion, duplication, etc. of Nets or Nodes
    • Supports user data fields for any Serializable Java object
    • Supports multiple threads
    • Supports standard Java I/O Streams
    • Includes basic graphics classes for displaying bayes nets
  • Thoroughly tested and reliable
