Easy Java Simulations Modeling and Authoring Tool

written by Francisco Esquembre
content provider: Wolfgang Christian and Félix J. García Clemente

Easy Java Simulations (EJS) is a Java program that enables both programmers and novices to quickly and easily prototype, test, and distribute Java or JavaScript simulations. Version 5.3 improved the generation of ePubs and includes a new "Export as MacOSX widget" when using Javascript. The Javascript preview can be displayed using your favorite Web browser. The Emulator preview option within EJS is now deprecated.

EJS version 6.0 will decouple EJS into two versions. One version will produce on Java simulations and the second version will produce only JavaScript simulations. The beta release of the JavaScript version is available for testing on the EJS Wiki.

Please note that this resource requires at least version 1.7 of Java (JRE).

EJS and the Modeling Cycle

The advantage of EJS for physics teaching is that it forces students to separate the model into logical parts and to separate the model from the view. Students learn the logic of computer modeling using loops and control structures and study algorithms used in professional practice when building models.
