General Purpose Libraries

nativecall

NativeCall lets you call native methods from Java without JNI code. With NativeCall, you can call all methods implemented in any DLL. It supports structs, Strings, primitive types (int and boolean), byte and char arrays and output parameters. NativeCall is implemented for the Windows platform.

 

joone

Joone is a FREE Neural Network framework to create, train and test artificial neural networks. The aim is to create a powerful environment both for enthusiastic and professional users, based on the newest Java technologies. Joone is composed by a central engine that is the fulcrum of all applications that are developed with Joone. Joone's neural networks can be built on a local machine, be trained on a distributed environment and run on whatever device.

 

retrotranslator

Retrotranslator is a Java bytecode transformer that translates Java classes compiled with JDK 5.0 into classes that can be run on JVM 1.4. Supported features: generics, annotations, reflection on generics and annotations, enums, autoboxing, for-each loop, varargs, static import, concurrency utilities, collections framework enhancements.

 

jline

Line is a Java library for handling console input. It is similar in functionality to BSD editline and GNU readline. People familiar with the readline/editline capabilities for modern shells (such as bash and tcsh) will find most of the command editing features of JLine to be familiar.

 

ostermiller-utils

Libraries for common tasks such as CSV, Base64, Circular Buffers, MD5, and Significant Figures.

 

protomatter

The Protomatter Classes is a collection of (hopefully) useful Open Source Java classes. The package provides the following: Syslog A robust logging system. JDBC Connection Pool A JDBC driver that maintains a pool of connections. PAS A lightweight application server framework. (JavaDoc) Object Pooling Framework A generic object pooling framework. These baseclasses are used to implement the JDBC connection pool, thread queues, mutex locks, etc. Misc Utility Classes Base64 encoder/decoder, blocking queues, work queues, mutex locks, and other stuff...

 

j.a.d.e.-java-addition-to-default-environment

The JADE library provides "Context Programming" which allows: - Objects to be allocated on the "stack" to avoid garbage collection and provide faster execution speed (PoolContext). - Automatic concurrency in low level method to take advantage of multi-processors (or hyper-threading) in a transparent manner (ConcurrentContext). - Thread-based inheritable local/global settings (LocalContext). This library also provides - Struct/Union classes for interoperability with C/C++. - A math package with the first (and unique) generic Matrix class to solve linear systems of any kind. - Physical quantities for which the dimension checking is done in the form of class-type checking (e.g. the division of a length by a duration returns a velocity instance). - Real-time XML parser with no dynamic object creation (the world fastest by a factor 2-3x) And much, much more...

 

jgap

JGAP (pronounced "jay-gap") is a genetic algorithms component written in the form of a Java package. It provides basic genetic mechanisms that can be easily used to apply evolutionary principles to problem solutions. The ground is laid for introducing Genetic Programming to JGAP in the near future! JGAP has been written to be very easy to use "out of the box," while also designed to be highly modular so that more adventurous users can easily plug-in custom genetic operators and other sub-components.
