Support for generics. Superset of the Java programming language. Compatible with existing libraries. [Freeware]

Java with assertions, spoken: jazz, like the music. Improvement of JaWA language extension. Gives Java the concepts of Design by Contract from Bertrand Meyer, and Eiffel, and extends them with new features. [Open Source, GPL]

An extension of Java and GJ to support polymophic methods while perserving static type information (no erasure). For research purposes.

A variant of Java that adds parametric polymorphism, first-class functions, and class cases and pattern matching to the language. The compiler compiles into Java byte code so the binaries can be run on a normal JVM. [Freeware]

Java extensions for high-level Web service development; Java-based high-level language to develop interactive Web services; merges main features of <bigwig> language into Java by providing explicit support for Web service sessions, safe ...

A generic protocol-based self-applicative interpreter for Java. Revolves around a generic reification procedure which can be used to reify any class of the interpreter.

Java with a spoonful of syntactic sugar: proposed set of additions to make Java terser and safer. Terseness makes languages easier to read, write, maintain. Ideas from Abundance (Byte Magazine Oct 1986), Eiffel, Pascal, Delphi, Smalltalk, PL/I, Algol-...

Java with support for generic programming in the form of parameterized types. Provides constrained parametric polymorphism, with advantages over some other proposals for adding genericity to Java. [Open Source, GPL]

Simplified subset of Java (supersedes Jr), and online environment for learning programming: simple, made for beginners, includes assertions and Design by Contract from Bertrand Meyer and Eiffel; class tested over 2 years, free accounts available.

Modification of the Java language designed to have true support for the IEEE 754 floating point standard.
