tXtFL is a strategy-based football simulator. Teams can be created from real stats on the web, built through custom designed plays, and then used to coach games or predict scores. Note that as of 2010, all new development is taking place at http://textflex.com/txtfl.
SimulME is a Java ME (J2ME) application with Queueing calculator, Stopwatch, Monte Carlo simulation, Random Number Generator (RNG), Probability distributions, Kolmogorov-Smirnov and Chi-square tests. It works with MIDP 2.0 and CLDC 1.1 profiles.
DCOPolis is a framework for comparing and deploying distributed decision processes in heterogeneous environments, including simulation in a virtual machine.
SimIS presents an agent-based simulation environment from multiagent research to simulate Internet-of-Services systems. The simulation environment bases on Repast Simphony 1.2 (http://repast.sourceforge.net/).
The BioSimz project aims to deliver a library (as well as the interface) to conduct large-scale biomolecular simulations at their atomic scales of detail. The initiative idea is to observe the protein crowding in vivo; it now can do much more than that!
A Java library that works with Java3D to simulate and visualize, in real-time, dynamics of multiple rigid bodies that are restricted by implicit and explicit constraints (e.g., robotics); designed for efficiency, ease-of-use, and extensibility.
JCrocus is a GUI (Graphical User Interface) that allows representing the network topology definition of microwave cavity filters based on the coupling matrix approach as well as simulating and plotting its frequency response
jQuantum is a Java program to simulate a quantum computer, to design quantum circuits, and to visualize the execution of quantum algorithms. Another main purpose, however, is to create images in your head, and thereby - understanding.
AMASBE (Advanced Multi Agent System Bullwhip Effect) is a bullwhip-effect control system for supply chains based on forecasts that uses Java Agent DEvelopment Framework (JADE).
netcdf-tools is a set of tools for creating netCDF files. It supports command line use on both Windows and Unix as well as use directly as a Java library. Written by CSIRO Australia and funded by the ANDS Australian Research Data Commons Project
An Interactive Fiction Player written for Java Virtual Machine. It implements the Z-machine and Glulx specifications and can be used either standalone or as an applet. The Z-Code/Glulx interpreter runs adventures made by Infocom and contemporary Inte
JDice rolls dice. A simple yet rich language allows to express several kinds of roll schemes, including any dice type, rerolling, selecting highest/lowest, counting, etc.
Database Driven RoboCup Rescue Server is a version of RoboCup Rescue Server (https://sourceforge.net/projects/roborescue/) which uses a database to store the simulation data in order to simulate a very large number of agents.
JSiBo is a small and extensible simulator for mobile robot with differentially steered drive system. It provides the end user with a simple way to test algorithms, by writing them in Java language.
A 3-d Constraint-based multibody physics engine written in entirely Java, aimed at real-time capabilities. The user can model bodies, geometries, joints, and parameters. See http://code.google.com/p/jinngine/ for source code and development information.
HealthCareSim is an SDK for rapid modeling and simulating care delivery systems using the discrete event simulation paradigm. A modular design and useful defaults will enable a Java developer to quickly build prototype models that can be extended.
