The jrunscript Utility

The jrunscript utility is a command-line script shell. It supports script execution in both interactive mode and in batch mode. By default, the shell uses JavaScript, but you can specify any other scripting language for which you supply the path to the script engines's JAR file of .class files.

Thanks to the communication between the Java language and the scripting language, the jrunscript utility supports an exploratory programming style.
