ObjectScript is a general purpose object-oriented programming language. It is designed to be simple to learn, easy to use, and powerful, combining the convenience of an interactive interpreter with many of the features of Java: a simple Java-like syntax, javadoc support, a class system (single inheritance), private vs. public fields and methods, exceptions, synchronization and threading, regular expressions, etc. Since it can be interactively interpreted, ObjectScript can be used to debug or learn Java systems. And since it supports extending Java classes and interfaces, it can add sophisticated scripting to an existing Java application.
