The K.U.Leuven JCHR System is an integration of Constraint Handling Rules (CHR) and Java designed with three aims in mind: user-friendliness, flexibility and efficiency. http://www.cs.kuleuven.be/~petervw/JCHR/

Planimetric Geometry (JCabri) is a rewrite of Cabri Geometry in Java. It provides solution for doing geometric constructions in 2D and exporting them as an animated GIF or Java applet.

JCalc is GUI calculator written entirely in Java. It can be run cross-platform on any OS with a Java Virtual Machine. It shall be portable, stable, and efficient.

JCharacterMatcher is an application for matching characters represented as graphs. It computes the distance between two characters. The smaller it is, the bigger is the probability that both graphs represent the same character.

[This project is frozen, but has an offspring with more features: https://github.com/jeffhain/jadecy ] JCycles provides treatments to compute cycles, or just strongly connected components, in directed graphs in general, or in classes or packages dependencies graphs parsed from class files (major version <= 51, else does best effort). It uses Tarjan's algorithm for SCCs, and Johnson's for cycles, with continuations instead of recursion, which allows to handle large graphs (< Integer.MAX_VALUE vertices). Requires Java 5 or later.

A java project to create a library that can calculate decompression schemes for diving. Different open source algorithms can be chosen to use for the calculation. For example Bühlmann and VPM.

JEPLite is a light-weighted (re)implementation of the Java Expression Parser (jep.sourceforge.net). The intention is to strip some of its not-so-often-used features, and thus speeding the rest. Includes expression optimizer.

JEXP is a small Java framework for the evaluation of expressions parsed from text strings. The code generated by JEXP executes very fast and has a small memory footprint.

JEquation provides an intuitive and fast way to input mathematical expressions into latex documents by using prestructured neural network based handwriting recognition.

A fuzzy logic toolbox written in Java.

A Java application for drawing dynamic mathematics features (as geometric figures, dynamic algebra) and for creating dynamic animations using geometrics tools. You can also export the figures to Latex2e pstricks, mfpic environment or JPEG, WMF, EPS image

Flight planning tool, designed for General Aviation pilots. Includes Aviation Weather Center METAR and TAFs queries.

Plotting of mathematical functions, including math expression evaluation

JGV is a Java applet that lets you embed movable 3D objects in web pages. Users can rotate, scale, translate, select and annotate the objects interactively. Also, JGV supports XML-based transmission of user events to the source web server over HTTP.

JHLib is a mathematical software library written in Java. With support for 2D,3D and nD mathematical calculations, also including Matrix, functions support and shapes. It includes a few none mathematical code, like filesearch and screen scraping.

Provides all financial annuity functions written entirely in Java 5: interest rate, number of periods, payment, present value, future value, type of payment. A Newton root search approach is included as an own Java class.

Lattices and ordered sets visualization tool

JLinAlg is an open source and easy to use Java library for linear algebra. It can do calculations without rounding errors. Features include: basic matrix operations, algorithms for solving Linear Equation Systems, inverting matrices, computing the determinant and the eigenvalues of a matrix. We have moved to Github: https://github.com/JLinAlg/JLinAlg

JMAT : Java MATrix tools package. Provides an easy-to-use class of matrix with MATLAB-like functions and syntax. JMAT also includes plots and histograms in 2D or 3D, an expression parser, and some statistic simulation tools.

Biblioteca para Java que implementa un potente evaluador matemático en español y un lenguaje estructurado de script, JMEScript, que hace uso de éste. Puede evaluar expresiones altamente complejas, que incluyen; * vectores * matrices * números complejos * números enteros y reales de precisión arbitraria, * expresiones booleanas * conjuntos * cadenas * diccionarios * grafos * correspondencias y relaciones finitas Permite especificar operaciones y funciones definidas por el usuario además de incluir más de 60 operadores predefinidos y más de 450 funciones predefinidas. También implementa un potente modo REPL que permite usar interactivamente la mayoría de características del lenguaje implementado por la biblioteca JME, incluida la importación y exportación CSV, HTML, JSON y XML. Puede consultarse la documentación de usuario y de desarrollador en la página https://miguelalejandromorenobarrientos.github.io/JmeDoc/ IDE JMEScriptGUI https://sourceforge.net/projects/j

Con este IDE podrá probar cualquier script escrito en JMEScript con toda la funcionalidad del lenguaje, incluidos gráficos 2D y conexión MySQL. La versión para Android, en este momento, tiene menos funcionalidad y ejecuta la versión 0.1 de JMEScript. Parser JME y lenguaje JMEScript en https://sourceforge.net/projects/jme/ Documentación en https://morenobarrientos-jme.site44.com/ Código fuente y UDL para Notepad++ en pestaña 'FILES'

Nuclear Fission Project is java API that suppose to be used in dynamical calculations of the nuclear fission process.

JOrrery simulates the motion of planets moving under gravity. It comes with a number of initial "scenarios" you can run, such as "The solar system", "Earth & Moon" etc. You can also add more planets during a simulation.

JQHull is a Brad Barber's QHull library (http://www.qhull.org) wrapped in Java.

JQuantity is a set of Java classes which enable developers to build scientific applications using quantities which are either exact or have known (bounded) errors. Quantities may include units, may be complex, non-scalar, etc. Extends java.math classes
